There are 2 mistakes in your post. First this: "I think it's very selfish to oppose H1B visas. America is wealthy compared to almost everywhere, and phenomenally wealthy compared to many of the places these H1B workers come from." Your reasoning applies to immigration, not to H1B visas. If America is wealthy and should share its wealth with others, then it should have open borders. H1B visas bring in foreign workers on a temporary basis, tie them to a specific job, and therefore leave them in a precarious situation, unable to demand pay increases. If you believe that America should share its wealth via immigration, then you should be fighting for a more generous availability of green cards, not H1B visas. About this: "The downvote button is not a disagree button. If I'm wrong, tell me why." Paul Graham has specifically said that the downvote button can be used to express disagreement. https://news.ycombinator.com/item?id=117171 https://news.ycombinator.com/item?id=117171 "I think it's ok to use the up and down arrows to express agreement. Obviously the uparrows aren't only for applauding politeness, so it seems reasonable that the downarrows aren't only for booing rudeness. It only becomes abuse when people resort to karma bombing: downvoting a lot of comments by one user without reading them in order to subtract maximum karma. Fortunately we now have several levels of software to protect against that."
