> Federal government in US is failing along with the rest of large scale western style governments. They are too big, cost too much, and have too many fundamental structural deficiencies.

How do you see those governments failing, and when?

When sorting countries by tax burden (as a percentage of GDP), then you will find that there are tons of extremely livable countries at the top (wealthy European nations), while basically everything under ~10% GDP taxation is a 3rd world disaster.

How big of a GDP percentage would you propose can a government take at most and not "invariably fall apart"?
