here's an idea, stop feeding the MIC with american troops, reduce the need to feed,and it will wither down to a manageable level, where scum are not needed.I am not sure what you really think can be done about it, should they start recruiting people with liberal arts degrees and impeccable PC credentials?
Priority 1. stop the perpetual wars, get the fuck out of AfPak yesterday, stop droning the planet. Also stop preparing for the NEXT war with China.
Such thinking is self fufilling.
reduce the needs for bodies to war, and you can be a bit more selective about who serves.
