I've edited my post. The last time around BLOTUS locked children in cages in Texas.
@Evoex - if you think he can actually do this without crippling the U.S. economy you're dreaming in technicolor.
I was going to put in a link to a YouTube video that shows the reality of the situation but don't have time to watch hours, if not days, reviewing the seemingly endless list of YouTube opinions, speculations, plans and legalities on the subject to find the right one.
IMO Donald Trump has spent 78 years of his life lying about anything that costs him power or money. He has become so good at it he can make up facts on the fly. He can twist laws and words faster than anyone can untwist them.
A lie can be made up faster than it can be disproved. Trump can make up a lie in a split second and if you are debating him you have to disprove that lie. You can spend days or weeks trying to find proof. By that time the subject has moved on and his supporters have accepted his word as the truth. You have lost valuable time that would have been better spent on your own positive thoughts.
It is almost impossible to prove something doesn't exist. You can look for ages and find nothing only to be told you were looking in the wrong places.
In a courtroom they put a limit on unreasonable claims. If your fingerprints were at the crime scene you could claim someone else has the same fingerprints. To disprove that it would require fingerprinting the eight billion people on the planet.
One video that I saw that seems reasonable said Trump's numbers were exaggerated and his powers were exaggerated.
The effect on the economy is reported to be dismal as it seems that undocumented aliens are the backbone of agricultural harvesting. Construction could be affected. It could get ugly if the source of cheap, non complaining labour dries up.
