If what you say is even remotely true, wealth would have never been passed from generation to generation and people would have never invested in stuff useful for the future.

What you actually mean is that there is a non-negligible portion of the population who act like children and won't ever be able to plan for the future, so we have to force them. But not only them, everyone into the same basket, regardless of their qualities and wants/needs.

Sure, a non-collectivist system would break a few more eggs, but isn't it the point? Rewarding the best/most useful behaviors seems like a fundamental need of a lasting society.

The curent system is problematic because it has pushed the equality ideology at the expense of personal freedom. The irony is that people who could benefit from better environment/luck/opportunities, will still get ahead at the end of the day. You are disproportionately impacting those who could have had better outcomes to "save" the ones who will have bad outcomes regardless.

It's all very cynical, and the peoples in power don't have to care, they are fundamentally not at risk...
