Where have we Republican gone wrong, when did we surrender our soul to a group of power mongers that economically keep raping the retirees, widows and orphans? Why should the middle cass be weighed down with a 50% marginal tax rate while Gates (and yes, Buffet too) pay a marginal tax rate in the 10% to 20%?
I don't understand why you ask this question post-Reagan. In the 40s-60s there were indeed some very responsible Republicans. And there still are some, to be fair about it. But when the party succumbed to the Reagan admin, that went out the window for the most part. Stockman's book itemizes it. That was when they developed their "Starve the govt" strategy, which allowed them to rationalize lowering taxes while not making the difficult decisions on how and where to lower spending. It became irrelevant, as they figured that an essentially bankrupt/starved govt would have to lower spending, wouldn't be able to afford to do the things they were doing.
Stockman at least itemized programs that ought to have been eliminated and gave reasons why they were unnecessary or wasteful. The new "Starve" strategy didn't require that kind of thought, and Gringrich/Gramm/Reagan Republicans didn't care to do it.
