Perhaps. But they are useful in the campaign to remove 12-20,000,000 Illegal Aliens from US soil, so they're tolerated.
We make it difficult for them to migrate here legally?
Correct.
In the heyday of American immigration (1840-1900 -ish) we were a nation of 20-80,000,000.
There was land to be had for free or dirt-cheap and there was a job of some kind for anyone who wanted one.
The nation was still growing and expanding and the extra warm bodies proved helpful in that building of a nation.
Today, we are a nation of 330,000,000 souls, the land is all parceled-out, we're done building, and we cannot even feed and house and educate and doctor and govern everyone properly and safely and happily.
We no longer need anywhere NEAR as many immigrants - in sheer numbers or as a percentage - as we once did.
The phukking Democrats let another 12-20,000,000 Illegal Aliens into the country in the Jan 2021-Jan 2025 time frame.
Quite possibly so that the 2030 Census provides another 20,000,000-ish souls to count for Democratic House seats.
Despite both earnest good-natured pleas and condemnations of their policies throughout that entire era.
It got so bad that the Republicans managed to re-install a shamed and censured Chief Executive to rid us of that plague.
We make it "difficult" for them to migrate here legally?
You're goddamned RIGHT we do.
And will CONTINUE to do so for the foreseeable future.
It is OUR country and WE decide whom are to be allowed-in and whom we will reject and send back to their old homes.
Our Country, Our Rules.
We require no justification beyond that simple bumper-sticker slogan -caliber rationale.
Less is More.
