The internet has already redistributed earth shattering quantities of wealth in record time. Besides, to actually solve the "real problems" (no true scotsman, but we won't go down that path) you still need massive amounts of capital.

Can't help but feel that there's a serious holier-than-thou tone throughout the article just because the author spent 6 months in DC. Thought experiment: who is helping the 1% more, people who generate products for a public company or people who work on pet political projects for the DC elite? (Not implying there's a right answer to that question, and not implying that's all the OP did with their time in DC)
