Dangers of CSME (CAFTA precursor)
When you have a single market economy, which CAFTA would create with Central America and the United States, you will get unlimited immigration, out of country students demanding in-state tuition, and unlicensed individuals working in areas where national and local licensing controls existed.
Here are some definitions of phrases that come out of "free trade" agreements:
the right of establishment==any foreigner can open a business in your country
the right of capital mobility==any foreigner can take capital out of your country , like remittances
free movement of labor== unlimited illegal immigration
national treatment == illegals must be afforded the same rights as "nationals" i.e. citizens
