I'm not American, and I understand the American government does evil things sometimes, but it also does a lot of good things for its citizens. It builds roads, keeps the skies clear, funds education, health systems, sues tech giants when they go too far, tries to manage the speculation/money markets, etc. To say "undeniably often working against the best interests of its citizens" is very hyperbolic. Most would probably argue that the government does not do enough, even conservatives (ex: controlling abortion or bathrooms, not that I agree).
The news are also not there to demoralize you, not as a primary objective. Anxiety and negative news do sell ads. I find public radio such as NPR do a wonderful job of balancing point of views, giving the facts, and provide some hope by explaining the underlying issues and possible solutions. Where I live, public radio is the only non-ragebait media that constantly puts pressures on whatever government is in power, and explains various points of views (while admittedly being more centrist editorially, angering both hard-left and hard-right).
I totally agree however with doing whatever it is you are good at, and that's a way to work towards improving the world.
