Yeah but the beauty in this approach lies is this: While Social Safety will level out the social inequalities in the long run, meaning that someday your wealth runs out and you are on food stamps like everyone else. This system freezes you social status. Management will still earn 100x more while others earn next to nothing. It might also cost more, maybe a lot more, but it stabilizes society. True there might be a shift downwards but this is inevitable; most people will be staying on their social stage or at least the distance will be the same to the guy above and under you. This seems to be very important. Always wondered why some guys are passing you just to stand in front of you at the same traffic light? Same same.

Isn't it healthy to frequently re-evaluate which government services should be expanded or contracted?

That's not what we see in practice. In practice, we see that any program that is deemed to benefit the "wrong" group is thrown onto the chopping block regardless of need and efficacy.
