While I understand the point that you are trying to make, comparing our system of government to Cuba's is ludicrous.
There are very few governments in the world smaller than Cuba's government.
One man.
You can be serious, can't you? Cuba is a Communist government wherein all economy is controlled by government. Here in the US, just a Socialist country, some economic activites are not directly controlled government (yet) .... but suffice to say, that 1/3 of the GNP is directly controlled by the government.
Oh yeah, the "huge divide" that you are talking about continues to shrink.
