That's my fear as well. The last wall to topple is a straight tax on capital. Sure, they'll sell it as a tax on the uber rich just like they did with the income tax, but that threshold will drop drop drop until the middle class is paying out on both ends: tax on earned income + tax on everything you have. Every year.
