Well, yes and no. There's plenty of fraudulent claims going around by Vets. I'm not saying that it reaches the level of fraud that is comitted by the welfare class, but there are people that are gaming the system in order to gain disability income and status when they are not, in fact, disabled, or their "disability" did not result from military duty.
I work with one such fraudster.
I have no doubt of that, but keep in mind that 100% of all federal spending on education, welfare benefits and other social services is fraudulent because it is not authorized by the Constitution. Once the latter is cut, we can worry about fraud when it comes to care for our veterans.
