All 3 groups I mentioned have zero right to be here, and many of those folks are victimizing American citizens.

A separate issue from whether removing them will have a material economic impact. There are industries that rely very heavily on labor that has "zero right to be here" - so even if those workers don't have any moral claim on a right to remain in the country, removing them can have a significant impact on those economic sectors.

They don't need to. They have a lot of folks to clear out just in the first 3.

Except, again, they haven't said they're going to limit themselves to just the first 3. Folks who are justifying the coming "mass deportations" are justifying them by arguing that they will be limited to these types of groups, but no one has ever said (let alone promised) that the deportation operation will just be those three groups.

I don't accept this, because it's the school of thought that says, "Let's just throw up our hands and let everyone stay". That's not acceptable, and also not sustainable in either the short or the long run.

Whether you accept it doesn't affect whether there will be a huge disruptive economic impact if you have mass deportations of all these people. You might find letting them stay to be unacceptable, but that doesn't mean it's possible to remove them without doing a lot of damage.
