Mexico is the 2nd largest supplier of oil to the US. They make billions and billions of dollars from us every year. They earn billions and billions of dollars from the tourism industry. Cancun, Acapulco, and other tourist destinations.

Could someone educate me on the reasons why they must abandon their own country?

I herd that 12 families own or control all the wealth in that country.

When the illegal Mexicans finally go back to Mexico, They can take the protesting skills they learned here and protest their own government for better conditions.
