Both of those videos contain useful information. I've seen the gumball demonstration, before. That really illustrates the point.
As to the orange haired guy who yells a lot; well, he really doesn't yell, that much. That's just all the media clips show. And, one can't be too mad at him; he's right.
Kelu is right, too. And, one point where the original video was wrong, was where the presenter claimed that no one was showing up for free stuff. Yes, they are. As far as they know, all they have to do is sneak in, squeeze out a kid, and they get freebies from the taxpayer forever, and so do their kids. Considering the conditions they left behind, they're much better off here. Plus, they can go to work, make tax free money, and since they don't mind squeezing 10+ people into tiny apartments, they have plenty of money to send to their families at home, who are likely saving up enough to pay a guy to bring them here, as well. Which he will gladly do, and probably make them carry some contraband across with them, as part of the deal.
It's assumed that there is some sort of right to be here. And, there is, as long as you were born here, to citizens of this country. Other than that, being here is a privilege. Sneaking into the country, no matter how dangerous the journey, does not earn you the privilege. It just makes you a daring criminal. The last thing we need in this country is criminal mooches.
Build the wall. Walls work, especially if patrolled by armed guards that shoot anybody who gets too close to the southern side of it. It worked in Berlin. Sure, a few folks slipped through, but it was no where near as porous as our southern border currently is.
