People are far more free in developing countries than countries like America, Australia, Canada. The three categories you listed are laughable and not even true. This forum exists because men are yearning for more freedom and not even because they're yearning to make more money abroad than they do at home.
Political freedom doesn't exist anywhere, vote against the two party system and see where that gets you. If it exists then we can be sure it's in a country too small to matter and probably in the developing part of the world. There is more economic freedom in developing countries, try to sell something on the street in America and you will be arrested, especially if it is something forbidden like raw milk. Your freedom is to be dominated from cradle to grave by corporations and wealthy landlords. In the developing world this happens but if you can't pay your rent you can sleep in an abandoned area or go into the wilderness and try to survive, you can't do that in the developed and free west you will be hunted down and arrested for trying to leave the plantation. Most importantly in the developing world you have the freedom to discriminate against people who don't share your values and traditions or your race to keep them out of your life and not allow them to interrupt your religious practices. Or even to keep them out of your country entirely. In America you have anti-discrimination laws and forced integration and racism and sexism lawsuits and wrongful termination lawsuits and never ending hysteria and witchhunts. And in the midst of all of this you have millions of illegal immigrants pouring in who don't respect the culture. They're not coming to America for freedom, in most cases they feel more free at home, they are coming to earn cash at the expense of their freedom. If you think the west is more free then you don't understand the meaning and the feeling of freedom.
Freedom is hard to define but feeling free is living without fear and believe it or not people in America live under more fear and stress than people in the developing world. Those 3rd worlders as you call them have the freedom to know who they are. Americans lost their identity decades ago, you could say they were liberated of it by Communist policies in the government. They were freed of their past and future because they lost the freedom to keep their own values, traditions and way of life. In that regard Americans do have more freedom than the 3rd world. The freedom to feel alien in your own homeland.
