They probably join up because it's one of the few jobs available....and you aren't asked to take peoples heads off with chainsaws or one of the other horrible ways the cartels have of dispatching their "enemies". And I'm sure a fair few of them do so because they genuinely hate the cartels and hope to do some good. BUT...the military is probably just as bad as the cartels at this point. Both sides killing each other, both sides doing whatever they can to make money, often times illegaly.
You know what, never mind what I said, I have no idea why ANYONE would join their military....I guess it's that, join a cartel, or die in the streets poor like a sucker.
I can see it. I wonder if a good kick in the pants might do long term good though.
I feel like a lot of the "problems" people have today are a direct result of them having it so good in all other aspects of their lives. They need to invent problems or imagine their small problems are bigger than they really are.
