No, 4.2 is NOT how many AMERICANS are unemployed. Itis a false figure that includes illegal aliens (who are not Americans)
You are just blabbering from pure emotion - how you want things to be, instead of how they ARE. Yes, revenue would be affected if DACA (or any illegal aliens) were to leave the US. They reduce revenue by 1) working off the books, 2) for those who are on the books, the make less $$, thus they pay less $$ than Americans, 3) some of they receive welfare thereby reducing available revenue
HA HA. Your jobs nobody else wants line was refuted totally 15 years ago when CIS did a study and found of over 400 occupation where illegals work, in 99% of them, there was a majority of Americans working there. Also, the toughest, dirtiest, and most dangerous jobs are routinely held by Americans, not illegal aliens (ex. coal miners, firefighters, police, troops in war zones. I've posted this 100 times,
You are brainwashed, and your fool ideas are the opposite of reality. If you booted ALL of them, consumer spending would increase at least $150 Billion/year, which is the amount last reported (in 2017) by the Pew Research center, that illegals send out of the country in remittances, and the economy would BOOST by $150 Billion/year much more because of the higher pay and thus greater disposable income Americans would have, working in the jobs the illegals work in now.
1. Mexicans CANNOT easily tunnel or climb over Trump's 30 foot tall wall. Only young, skinny, athletic men could do that, leaving out women, children, fat men, older men, and men not in top physical condition.
2. Court cases don't go on forever.
3. Where it is impossible to build a wall, it is also impossible for aliens to move through there.
4. Cost of maintaining the wall would be economical, relative to the costs and harms of illegals entering the country. See the list in Post # 130. It is logical and very compelling, and most of it doesn't need "sources". It us self-explanatory

by COMMON SENSE. (except to idiots) This points that do need sources, have them (ex. wildfires)
