Tad DeHaven at Cato points out that even Tea Partiers succumb to the temptation of using the Federal budget to buy votes.
The only solution, the ONLY solution, to this problem is to limit government – limit what it can do (with a strong, restrictive, limiting Constitution) and limit how much money is has with which to do whatever it does (starve the beast). Else, public choice policy turns out to be correct (as Don Boudreaux points out). That is: spending other people’s money on yourself or on others is really easy to do. Or, put another way, When A and B engage in a transaction that is beneficial for either or both A or B while detrimental to C, if C has no say in the matter, then it is easy to consummate the transaction.
