See, I'm on board with your point there, and I would love to see how much truth there is to it. Those countries have renegotiated many agreements and some now have socialist governments which are doing quite well, despite the fuckery the US put them through.

The post doesn't leave room for ambiguity or nuance. It says "x is true". That's why it's dumb and arguably a net bad. Quick little feel good statements for such a complicated issue just help people on the Internet feel better by liking or up voting while harming any actual progress. So fuck the person who wrote the original thing and fuck OP for spreading it.
