Idk what subs you hang out in, but in most of the subs I follow one of the easiest ways to farm upvotes is to simply trash on the USA. I see one of those "Stop complaining about your life. There are literally people living in The USA." memes[0] at least once every couple weeks and it always performs well. "America bad" is a very well known trope in the Reddit comments.
