Wasn't there a draft for the Vietnam war? And probably also Korea? One of the issues I can remember there is that less-well-off people couldn't buy themselves out of the draft. This affected minorities especially.
Vietnam yes, Korea yes, laughably easy to dodge in both cases for poor and rich alike.
Yes, but not everyone that went was drafted. Obviously, I make an exception for draftees. Poor people got fucked over the most. Still don't deserve a holiday though, let alone two, especially when dodging was an option.
