The truly rich, by virtue of being actually wealthy, can structure their finances to avoid most of the worst taxes. Up-and-coming strivers can't do that.
Regardless, If we follow that logic to absurdity, why don't we directly just pay out the rich from the earnings of the poor? They are going to get it anyway.
Laws now seem focused on an iterative stemming of the tide. In this case, eventually the laws (hopefully) get good enough that the rich can't just can't restructure. In that way, it is no unlike iOS base-band. Is it secure? Heck no. Yet, is it secure enough (with a platform open enough) that the hacking is not worth... for most, yeah.
