this is true, I asked the IRS agent to define wealth and they couldn't do it, therefore meaning I no longer have to pay taxes
Worse: Most of the circumventions of income tax are to increase in wealth without having income (as recognized by the tax system). A wealth tax is therefore a fix for your complaints about income tax.
Look, I'm not convinced a wealth tax (or worse, cap) is the answer. I suspect it may be worse than the disease. But your arguments against it seem pretty weak.
