A big % goes to Military families in salary, free medical, and retirement pay.
BS! When I was active-duty in the mid-to-late 90s I knew many military families on FOOD STAMPS. These were hard-working patriotic men and women who willingly lived below the poverty line due to the idiots who determine the military salaries (Congress). Military pay is simply pathetic.
You are correct that military pay is bad, that the VA medical system is crummy, etc. but I'm also correct that the US gov spends a ton of money on Military families. The thing that ties both of the comments together is typical government inefficiency and waste.
Try selling any product to the military and you'll have 100's of dollars of paperwork for a 50 dollar product, then the product will get shipped from one warehouse to another before it ends up where it is needed. The procurement supplier documents for something as simple as a tongue depressor will ask 1,000s of questions on a 300 to 500 page form including if you are in the nuclear weapons business.
I never really understood why the Republicans did not hammer the Democrats about the VA during the debate on Gov take over of private insurance. If Demos can't fix what they are already responsible for, why give the US gov more responsibility.
