I'm sure they're all very wealthy and great examples of why free market capitalism works. At least they would be if free market capitalism even existed, which it doesn't, its just as unstable a concept as hard socialism.
I'm all for a free market, with safeguards in place which allow all people to work and trade freely of course, in other words not so free as to allow monopolies. I want a mixed economy with a combination of capitalism (if only to avoid upsetting those who fetishise it) and social welfare in place to make sure that those who aren't as fortunate or as well-endowed with business acumen are well taken care of.
Universal healthcare for instance makes sense in so many ways, here in the UK I would be dead were it not for the NHS, literally. I've had medical issues that would render me poison to insurers, to whom money is more important than life. The fact that Americans spend more money per capita on healthcare than any country with nationalised healthcare discredits their system right out of the gate.
