Blame the voters.
They really don’t want spending cuts, not for their pet programs, oh sure they want to cut the programs they don’t care about.
Exactly its the voters! Over the years they’ve discovered they can tap into the public purse.
Anyone who takes a serious look at federal spending will its one big system of transferring wealth from one segment of society to another. Conservatives howl about welfare kings\queens, government salaries\retirement etc spending are fine with these wealth transfers if they’re firmly attached to the government teat (Of course only for the best of reasons!) receiving the money - entitlements! ( As most are!). I demand cuts & reform, my neighbor complains I’m breaking his rice bowl. My neighbor demands fiscal prudence I claim he’s goring my ox! That’s the genius of the system, everyone is at the Treasury trough! The public at the trough in one form or another is the majority of public spending! This is why it’s so devilishly difficult to reform.
