If anything, increase it (so long as it is put to relatively good use). The endowments granted to the various universities across the US have made a great many contributions such as the University of Florida to agriculture down here.
If anything, cut Defense spending by a significant amount.....there is no reason for us to be maintaining hundreds of bases overseas where there is no threat(Germany, Japan, Italy, S. Korea). Make Social Security a personal, low-interest government bank....what you, as a person puts in, is what you get out of it when you hit the retirement age. Cut social services by a significant amount......there is no reason at all for able-bodied people to collect welfare, free housing, free cell phones, EBT cards, and free electricity/energy to their free homes. Reduce or eliminate wasteful foreign aid, especially to hostile nations.
Tax the shit out of soda, candy, chips, all junk food on top of fast food....implement taxes on strip bars(Gentleman Clubs my ass)...give nice, scary warnings on junk food and fast food as they do on cigarettes.
Woops....sorry.....Rant Off
