My advise to the typical young person who is interested in politics:
Remember that somewhere in the world there is someone who is both smarter than you and more knowledgeable than you, and has completely opposite political views. This person might even be a friend, a family member, or a future version of yourself. With that in mind, why are you so sure of yourself? Spend less time talking, more time learning.
As for China, yes he did oversee the opening of China with the world, though this can hardly be construed as a left-wing goal when many right-wing Cold warriors supported this because of the opportunities for trade and isolating the Soviet Union after the Sino-Soviet split.
Nixon was not ideological, he was on the whole quite moderate and pragmatic, but still firmly right of center.
...and the genuinely rich people have things like the Channel islands, the Dutch sandwich and whatever needs to be done when the taxman finds your latest gimmick.
Take healthcare for instance. Many Europeans receive, on average, way better healthcare than average Americans, and even when you factor in the taxes they pay for it, it comes at a fraction of the cost. Again: on average, Americans pay a lot more for healthcare than Europeans do, without receiving better service on average. How is that any better?
