Oh, you mean the preference for women, minorities, and veterans? Yeah, that's an interesting issue. It's great in theory, but in practice ends with quite a bit of additional bench stuffing to increase preference. And then to start a company and compete for contracts, even if you're a rockstar engineer who just happens to be white and a man, good luck competing against an 8A. It's hard to complain, because I see the value, but at the same time, UGH.
Quite honestly, it creates a class of "tokens". They nominally have jobs, but their real job (for the sake of the company being awarded the contract) is to simply be a token. Certain minorities count for more than others.
