A hermetically sealed border ... would be astronomically expensive and (ineffective), considering our heavy reliance on undocumented labor for an increasingly diverse range of labor-intensive industries. It runs counter to our economic reality.

If dust mites or dander are triggers, remaining inside in a hermetically sealed house can increase the likelihood of an attack. Also, people tend to have more colds and upper respiratory infections in the winter, so being around such people in close quarters can increase the chances of an infection.

We don't know how many of those are documented or undocumented.

It's very expensive to be me. It's terrible the things I have to do to be me.

Labor was the first price, the original purchase-money that was paid for all things.

Some does in labor really make a racket, but she didn't make any noise at all.
