The "wall" is a fence really, but whatever.
It is useful in slowing down physical crossings in certain areas chosen by coyotes and such as preferred places to gain illegal entry. If they want to keep using that to slow down the flow a bit in spots where it is easy to cross, fine.
Simple geographic surveys of places known as popular crossing areas should make it easy to identify where to build it and where it is a waste of funding.

Anyone with $150 can go to a hardware store and by a cordless grinder and a cutoff wheel and make a damn door through the thing in ten minutes, but OK.

It just doesn't fix any actual problem.

It's a band aid - just slowing down a rapidly bleeding wound that we have no easy way to treat.

Netherlands, Germany, France, Spain, Italy, Norway, Sweden, Greece, Hungary, Poland and on and on and on.

Any nation like these that is viewed as a better alternative by those fleeing war, famine, or general impoverishment - they are all facing the same crisis we are. They are all flooded by refugees, asylum seekers and an inundation of migrants just hoping for a better life.

Putting a fence at the border won't change that. They'll keep coming any way they can. And they'll find new ways.
