My family migrated to Mexico from America four generations ago, and they're staying there. Not because Mexico is legally freer, but because Mexico is freer in practice because the laws are never enforced.
I'm the only one in America.
For example ... If you want to build a house i nMexico, you build it. No need to get permits and inspections. Nobody pays income tax, even though there is 30% federal income tax. Want a water well .. you just drill it and hide it. Nobody gets well permits up front. They drill and hope they can get a permit in the future. If not .. oh well.
However, the water thing might change with the Mexican federal government declaring ownership of all the water in Mexico, but I presume that those with permits might lose their wells, and those with illegal wells will continue to have them.
Guns are illegal, but everyon has them. It's a fairly lawless conutry, and the closest thing to the Libertarian ideal that I've ever lived. People are more concerned about what the Cartels will do than what the government wil do.
