This is short sighted. Their American born children and grandchildren will be competing with your children for high paying jobs. Children and grandchildren that weren't supposed to be here. When the Hispanic population blows up to 100 million, then what? Also it's an outright lie that they don't depress wages. Who's going to pay a college kid $50 to mow a lawn when an immigrant will do it for $20?
Your comment is also short sighted. You talk about a population booming with no growth in a countries economy?
More people = more consumers = more demand = more jobs created.
The biggest threat job growth is outsourcing and automation in certain industries.
