Why do people who come here illegally tell us how to run our country?

Mexico has 50 percent poverty, no jobs, president is cartel whore, Venezuela is communist ruin, and poverty, South Africa people are killed for being white, Somalia isn't much better its not even a functioning country and Afghanistan are run by taliban and have child marriages, but if you come to the united states and hate it cause its not like your home country then why not go back? Makes zero sense.
