We agree that that current welfare spending levels --65% goes to re-distribution-- are destructive and way out of line. There's most probably some optimum level where allocating recourses to "promote the general welfare" is appropriate, but we'll have to have a lot of spending cuts before we get anywhere near there.
“[P]romote the general welfare” is an objective of the Constitution, but it is only achieved through the enumerated powers of the Constitution. Anything else is unconstitutional.
