The excuse that they're taking our jobs is for losers.  Period.
The unemployment rate for the US in May 2017 was 4.3%.  4% is incredibly low.  What jobs exactly are the dreamers taking from you?  What, low paid gardeners?  Nannies?  If you are losing out on job competitions, its not because you went up against a dreamer, its because YOU WEREN'T QUALIFIED!!!
I'd wager that the vast majority of these people are hard working and honest.  They pay taxes and contribute in a positive way to our country, yet we would send them back to a country they probably cant even remember and have zero bonds with.  We would take away there lives.  Why?  Because a bunch of losers who cant be bothered to become either adequately educated or trained to meet the requirements of a new employment era have decided that, as per Trump, THEY are the reasons things aren't working out so well.  
If the above reasons aren't enough, we'll need every tax payer we can get to help dig us out of our debt.
