"illicit migration is a continuing problem; Cubans attempt to depart the island and enter the US using homemade rafts, alien smugglers, direct flights, or falsified visas; Cubans also use non-maritime routes to enter the US including direct flights to Miami and overland via the southwest border"

Just a quote from that url posted above. Cuba may have good doctors, and they may have plenty of little kids that can read, but here's the thing: 1.) not all doctors get the same amount of money from the government. The Cuban government, which is more of a dictatorship than a communism, will pay good money for doctors that cater to high officials within the government. This means that the public does not always see these excellent doctors. So it's not really the system that works in that case, just the greed of those in charge. 2.) the literacy rate is not a good indicator of intelligence. All the literacy rate looks at is if they can read. Not the level they can read at, or what they read. If they can read Cat in the Hat, they're literate by those standards.

Tax History lesson: The American Revolution was in part started because of a 7% income tax imposed upon them by the British Government. Today American income tax is roughly 30% depending on benefits, dependents, etc. What's the main difference? In the early 20th century Americans asked the government to create an income tax in order to help pay for social services such as transportation, development, etc. They let themselves be taxed because they benefited from it. The point I'm trying to make is this, if the tax money is put to good use, then taxes are good. When the taxes are used to pay $200 for a hammer or $100,000 just so a cruiser can go out on a Sunday instead of a Monday, then taxes are bad.
