But this supports the whole idea of a basic income - if everyone is able to live without working, they can take risks such as going to University, starting a business, etc...
A lack of social net prevents risk taking and severly limits mobility, creating a 'have-not' class and keeping them there for the most part.
Because if you say that "if you restrict that to only those who are already well-off", their parents probably weren't or their parents' parents etc.
There are many occupations that really only require hard work and little risk that has big payout.
The end result here is that no, life isn't "fair". But by and large, a person that has the ability to take risk, does and succeeds will create that ability for others to do the same in the future.

I think we could do better, but I'm not sure what you are saying is correct, either.
There's rather clearer data that the gap between rich & poor continues to widen in the US, which makes it a bit more bleak that going from poor to rich is still a rough uphill battle.
It's also fairly disheartening when you think of all the things that have changed in the past 50 years, many efforts that should help social mobility. Attempting to stop pervasive lead poisoning, lots of grants and policies to help get poor kids through basic and into higher education, legal and other sorts of efforts against sexism and racism... all kinds of things intended to hopefully make the playing ground more fair for everyone haven't actually moved this particular needle at all.
For a bit more context, also look outside of the US. If you want to live the American dream, you'll have a much better chance in Denmark. Reference here (though I read about it elsewhere a few years ago... can't remember orig src): https://en.wikipedia.org/wiki/Socio-economic_mobility_in_the...
Of the 9 developed countries in that study, only the UK ranked worse than the US.
