Question

What is the main source of Mexico's income?

Answer 1

yes, it's oil, tourism, money mailed from the US, but above that, it's drugs.  drug trafficers now bring in the same amount to the mexican economy as tourism.  albeit not LEGAL, it's still income.

Answer 2

The main source of Mexico's income is revenue from state owned Pemex (oil producer).  I think the second source is tourism and the third source is money sent by immigrants in the US to their families in Mexico.

Answer 3

I heard recently that tourism is now the third largest source.  Oil and money that immigrants send home to MX jockey for first - depending on the oil prices.  Not sure how accurate this is, but it's very interesting.  Imagine how much worse their economy would be if Mexican workers now in the USA returned home to MX!
