Re: Trying to maximise the pain
Well they would be impacted when the firms go belly up because they haven't been paid. And your 'no reason for the government to be as big as it is' is just counting angels on the head of a pin. If a country needs a park service it needs a park service. Whether you go - Taxes - Govt - park ranger or you go Taxes - govt - Crapita - park ranger makes not a whit of difference, except in the second case you are paying for less park rangers and more executive jets, plus you will probably find that the man in the middle says he lives in the Virgin Islands and doesn't have to pay tax.
(and I know you said non-profit but non-profits have overheads and executives too)
