"This is a good way to destroy the military and the Republican Party in one easy swing."
Did you actually read the proposals? Two of them get rid of some of the more wasteful porkbarrel aspects of military life (dual exchange systems and stateside schools). The third gives the servicemember incentive to manage his family's health care wisely.
Are you someone who favors government waste, as long as it's wearing BDUs?
Soldiering is not a normal job. Men take the job expecting to be, possibly, killed in action. In return they expect their families to cared for.
They don't expect high salaries, and they don't get them. They do expect "quality of life" matters to be covered for their families. Health care and schools for their kids is all a part of that.
When a man signs on as a soldier, he is making a bargain. He is willing to risk the life of his family's primary bread-winner, if you promise to take care of his family. Break that promise, short-change that promise, and he will have to guarantee his family's well-being himself.
