My point is you are babbling nonsense about a hundred years ago while thousands of UNKNOWN ILLEGAL IMMIGRANTS are being shipped all over the country EVERY FUKKING DAY! I guess you won't think it's a problem until they start camping out on your lawn.
People have been coming over that border and settling in the US with their kids becoming multi-generational citizens and OMG..,even Republicans.
The problem isn't the people coming, they've been coming for over a century every day, every month, every year, for over a hundred years.
The problem is White European bigotry and the ever growing fear of losing their inherited right to superiority over all other ethnic groups around the world.
Your problem has no solution. Perhaps it would be a good idea to start treating these groups better for the inevitable day when White European Christians are a minority. You know, build some Karma?
Anywho...
The actual problems. The flow, the cost, all of it has solutions.
Enforce e-verify then criminalize failure to use the system
Issue work permits to those already here and those released from processing IF AND ONLY IF EMPLOYMENT AND HOUSING ARE PROVIDED.
They pay taxes but are not eligible for Medicare/SS until permanent residency is granted.
The payroll taxes they pay will be used to cover their social services costs.
Control flow such that inbound flow is matched by those placed with employment and housing.
Set a maximum capacity at border facilities.
Once they're full, the flow stops (Trump's stay in Mexico)
Increase immigration quotas from non-Western European locales.
But you folks aren't interested in addressing problems, just whining about them.
