Well, I may get hammered for this, but I know more than a few Vets, and some are fakers.
My tour in Vietnam was mostly in safe areas, only saw a few dead/wounded American servicemen. It was enough. Since then I have lived around or worked with many Vietnam era vets who have good reason to apply for funds. One neighbor had a lot of his body shot away, and is 100% disabled, and his mental problems are more related to his physical situation than his actual service. There is so much he can no longer do with half his appendages gone, and his remaining hand more like a claw. The inactivity of his life is hard to take. Another became a dentist after his service, then a decade later his hands started going numb, from exposure to Agent Orange. Hard to do dental work with hands that don't work so well. He isn't getting much for that, but every little bit helps. His wife has to be the breadwinner for the family.
However, I have also worked with some who just milk the system. One guy, an Air Force type, never served in Vietnam at all, but claims to be ridden with guilt because his "comrades in arms" suffered while he did not. That may have also been his excuse for spending his income on toys for himself and letting his children go without needed dental work. Another who I worked with is a slacker in every sense of the word, and continually applied for higher percentages from the VA as he approached retirement from the job that he seldom did or did so poorly that his employer worked hard to get an early retirement for him. He brags about his ability to play the system. Seems 2 Purple Hearts are worth a lot these days. He never says where or how he was injured, and we cannot tell by looking.
One more just keeps using his veterans status to claim that the country, and the company he works for, "owes" him. He tried to get me involved with VFW, but his branch is more of a drinking club than anything else. I think his handicap is an addiction to self pity.
And I know a few more who will not talk about their service, at least not with someone who never served. Those are the ones who are probably worthy of some compensation, but do not apply for it.
Like welfare, the funds available should be used for those who need the help. Those who do not need it are stealing it from those who do.
