An actual free society does its best to balance different things, like individual rights versus the good of the whole. When done well, protecting individual rights enhances the good of the whole.

The reality is that a 100% estate tax mostly will hurt the middle and lower classes. The ultra rich will get with their lawyers, set up trust funds while they yet draw breath and find other loopholes.

Same as it ever was.

And while wealth inequality is a genuine issue, there's much worse things that grow out of trying to prevent people from being wealthy at all. It's absolutely the wrong goal. The goal should be to not exclude people from the benefits of living in a wealthy, developed nation. It shouldn't be trying to arbitrarily and spitefully rob the rich.

> So in a free society, power should be given out according to the whims of the already powerful?

It depends on what you mean by “power”. If by “power” you mean money then the answer is yes, if it’s their money. The same applies for the not-so-“powerful”.
