The biggest fallacy in politics is that we need "another Reagan" or more "Tea Partiers" in Congress if we want to save the country. Granted, either would certainly help, but America's structural problems are much bigger than any personnel issues we have in D.C. Even if you're an extremely talented craftsman, you're going to have trouble building a house if the only materials you're allowed to work with are sand and straw. It wouldn't matter if Kobe Bryant, LeBron James, and Kevin Durant were all on the same basketball team if they were only allowed to put three players on the court at a time. If you're trying to build the world's largest farm in the middle of the Sahara Desert, it probably isn't going to matter if you have state of the art equipment.
We have the ability to fix every problem that's confronting us as a nation, but until we stop making cosmetic changes and start addressing the underlying, intractable issues that are ruining the country, we're unlikely to make a lot of progress.
1) Insufficient Turnover In Congress: Because of gerrymandering, political polarization, and a lack of term limits, Congress has turned into a stagnant pond. In most states and districts, that notorious Third World dictum (One man, one vote, one time) has become the rule. Unless a politician upsets his own side's interest groups or gets caught up in a major scandal, an election to Congress is likely to last until a politician is ready to retire to a beach somewhere. Career politicians produce bad outcomes for the country. Members of Congress make draconian laws because they don't expect to have to live under them as citizens. Additionally, politicians who view being members of Congress as their "jobs" are likely to feel very comfortable selling out the country to special interest groups because they contribute to their campaigns and it benefits them personally. As a practical matter, we've gotten to the point where there's not much difference between most members of Congress and nobles from 500 years ago who ruled because of their family names and given that, it's no surprise that many of them "rule" just as poorly.
