True enough.
Assets are not subject to income tax. So for one to propose punitive INCOME taxes after one has acquired great ASSETS is really no sacrifice at all.
Rather they are merely cutting off the rungs of the ladder behind them, cutting off any up and coming competition, and preserving the status quo with themselves at the top.
How true! I once read somewhere a long time ago that the super-wealthy robber barons were the ones who most in favor of the income tax in the first place.
