I certainly hope that the US government break into the secrecy code of the Swiss banks where a lot of ill gotten tax evaded wealth is stored. Am sure a lot of politicians also have goodies stacked away there which is why this move will never fructify.
I don't - to the contrary, I hope that there are more places to put ones' wealth where the government thieves can't steal it. The amount of earnings confiscated by the government far exceeds the cost of its constitutionally mandated duties.
The only "ill-gotten, tax-evaded wealth" that I see is in the form of welfare given to the lazy base of the democrat party year after year.
