Do you know that the Koch brothers are actually pretty big philanthropists? The way you and I are going at this, we're getting nowhere. Of course extreme inequality and oil barons are bad (I'm all for highly progressive taxing schemes to rectify that problem), but tech and tech giants are not without some serious stains -- tactlessly spending millions on weddings (destroying ecologically sensitive areas, cutting down trees without permits), being a culturally homogeneous monolith that keeps "others" away, etc. etc. Clearly both tech and extreme wealth disparities are problems. We can do something about the tech part though -- don't work for them, denounce them for their immoral behavior, try to convince the regular folks that we're just working 9 to 5 to put food on our kids' plates, etc.
