That is the wrong question. The problem isn't about having people leaching the system there are other attributes towards wealth than raw survivaval we want to feel special and worth while, those who freeloading willingly really have some mental problem that should be addressed. The real question is on the other side if there are no corporations or rich people what will prevent people going that extra mile where it really suffers.
Let's use Musk as an example against all odds he is pushing clean energy and making money off of it. A government really would still stick with fossil fuel just because the risk of failure is low and the jobs for it are well defined.
The social imbalance is needed for progress.
But we need to make sure those at the bottom are not stuck. That is where the problem is.
