Q1: Should governments be responsible for reducing income inequality?

I think governments have both a moral obligation and a practical interest in addressing income inequality, though the debate is about how far they should go. Societies with extreme inequality face serious consequences: social unrest, lower social mobility, weaker public health, and even political instability. When wealth is concentrated in too few hands, democracy itself can be distorted, as the rich gain disproportionate influence over policy. Governments have tools to address this — progressive taxation, welfare programmes, investment in public education, and antitrust regulation. However, there's a legitimate debate about how much redistribution is too much. Tax rates that are too high can discourage investment and economic growth. The challenge is finding the right balance: enough redistribution to ensure a basic standard of living and equal opportunity, but not so much that it stifles the economic dynamism that creates prosperity in the first place.

Q2: Is it better for a country to be ruled by experts or by elected politicians?

This is one of the oldest debates in political philosophy, and my view is that democracy — despite all its flaws — is still preferable to rule by experts. Technocracy, as rule by experts is called, has genuine appeal. Many policy decisions — about public health, monetary policy, or environmental regulation — are highly technical. Why should the average voter, who may not understand epidemiology or economics, make these decisions? Yet history shows that unelected experts, however well-intentioned, can become detached from public needs and unaccountable when things go wrong. Democratic accountability, however imperfect, is the only mechanism that ensures leaders respond to the public they serve. The ideal model, I think, lies somewhere in between: elected politicians set the broad direction and values, while independent expert bodies — like central banks or public health agencies — handle the technical details within that framework. The key is that experts advise, but the public ultimately decides.

Q3: How effective are public campaigns in changing people's behaviour?

Public awareness campaigns can work, but they have significant limitations, and I think they're often overrated as a policy tool. Anti-smoking campaigns, seatbelt advertising, and anti-drunk-driving messages have genuinely contributed to changing social norms over decades. But these successes worked because they were paired with legislation and economic incentives — bans on smoking in public places, higher taxes on tobacco, fines for drunk driving. Campaigns alone rarely change deep-rooted behaviour. Telling people to eat less junk food or exercise more, without changing the environments that make unhealthy choices easy, usually has minimal effect. Behavioural research has shown that "nudge" approaches — changing the default option, making healthy choices the easy choice — are far more effective than simply telling people what to do. So I'd say public campaigns have their place, but they're most powerful when they're part of a broader package of regulation, incentives, and environmental design.

Q4: Should governments spend more money on public transport than on roads?

Absolutely — and I'd argue that most governments have been getting this balance wrong for decades. In car-dependent countries like the United States, massive subsidies for highways and cheap fuel have encouraged suburban sprawl, air pollution, and sedentary lifestyles. Public transport, by contrast, is more efficient, cleaner, and more equitable. A high-quality public transport system reduces congestion, lowers emissions, and gives people who can't drive — the young, the elderly, the disabled — greater independence. That said, the answer depends on context. In sparsely populated rural areas, public transport simply isn't feasible; roads are essential. The challenge is in cities and urban corridors, where investment in buses, trams, and trains delivers far higher social returns per dollar than more highways. The mistake many cities make is building more roads to solve congestion, which simply induces more traffic — a well-documented phenomenon. The solution isn't more asphalt but better alternatives.

Q5: What role should the government play in supporting the arts?

I think government support for the arts is essential, not because artists deserve special treatment, but because the arts are a public good that the free market will underprovide. Left entirely to commercial forces, the arts would gravitate toward whatever sells — pop music, blockbuster films, mass-market novels. Important but less commercial art forms — experimental theatre, contemporary dance, classical music, literary fiction — would struggle to survive. These are precisely the cultural contributions that, over time, define a civilisation. Governments already support the arts indirectly — through public broadcasting, museums, and arts councils — and most people accept this. That said, there are legitimate concerns. When government funds the arts, should it also decide what's good? Censorship and political bias are real risks. The best model is arm's-length funding — the government provides money, but independent expert panels decide how it's distributed, not politicians. This protects both artistic freedom and public accountability.

Q6: How can governments encourage more people to vote?

Voter turnout matters because democracy's legitimacy depends on it, and there are proven ways to increase participation — though some are more controversial than others. The simplest approach is removing barriers: making registration automatic, holding elections on weekends, allowing postal voting, and making polling stations easily accessible. These administrative changes reliably boost turnout without favouring any political party. Some countries go further and make voting compulsory — Australia, for instance, has near-90% turnout. Compulsory voting is controversial, but it works. However, technical fixes only go so far. The deeper reason people don't vote is that they feel the system doesn't represent them or that their vote doesn't matter. Reforming campaign finance, reducing gerrymandering, and giving voters more meaningful choices would address the root cause. Ultimately, though, voter turnout is also a cultural issue. When voting is seen as a civic duty — like paying taxes or serving on a jury — people participate. When it's treated as an optional consumer choice, many opt out.
