> it's impossible to use such reports to make general claims about what kind of government is better.

Across 1000 years of history, yes. But as already noted in those cases objective health/longevity differences can settle the issue. The report can then be used as a one source of evidence in comparison between the setup in countries today.

> Because "people" can't make it happen in societies where the government controls all those things.

People can vote for parties and candidates with an agenda to abolish public funding of education and infrastructure, but people choose not to. Very few vote for the libertarian party in the US for example.

> And even with all those advantages, people still do try to opt out.

In the countries that score best in terms of happiness and life satisfaction there is wide and strong popular support for an extensive welfare state with tax funding of schools, infrastructure and health care. Is your view that large majorities of people in those countries over decades are consistently mistaken about both their reported happiness and their support for their welfare state?

> If government-run schools in the US, for example, were really so great, there wouldn't be so many people trying to get their kids into private schools, or home schooling.

The US is not in the top of the report I cited and has many problems in the schooling system. One underpinning factor is segregation (ethnic and socioeconomic).

> school vouchers

... are tax funded, so is a variant of an extensive welfare state on the funding side. A drawback with such a mixed setup (public funding of private provision) for schooling is that it often requires even more regulation, oversight and middle men activities due to for profit and competition dynamics. The US health care system is a prime example of how cost-ineffective such systems can become compared to more straightforward public provision of health care in other countries.

> Only if they exist to be surveyed.

Are you saying you don't think there's any gradual differences in how extensive the welfare state is among the countries listed in the report?
