How does the U.S. benefit Mexico & how does Mexico benefit the U.S.?

Mexico benefits the United States by supplying them with workers. Though there are many illegal immigrants who find work here, they usually take the jobs Americans do not want to take. They also do not pay income tax but they do pay a sales tax which also benefits our economy.
The United States benefits Mexico by giving them jobs and also providing tourists. Though both benefit each other because of their trade partnership.
I don't know how else they benefit each other. I know there are more ways but I can't think of anything else.
