Of course, the answer is "yes". The illegals are stealing with every act they take while here, starting with fake Social Security numbers and innumerable other acts of fraud (mostly felonies if the laws were to actually be enforced).
But more important, they are stealing the livelihood of the poorer American citizens who want to work. And PLEASE don't bring up that tired old tripe about "jobs Americans won't do".
I used nearly identical words in another forum last week.
They are dooing jobs Americans USED to do, but for less pay........
