> As other people pointed out, it's not like there wouldn't be grocery store staff and that's the end of it. The demand is still there. And when the supply is low but the demand stays the same, the wages go up.

The reality is that this doesn't happen when it gets really bad. A few real-world examples:

Nebraska had (as of December 2016) 11 counties without a lawyer[0].

In California, when immigrant labor started getting deported, celery farmers kept increasing wages to attract new labor, and even after more than doubling their wages, couldn't get enough people to pick all the celery.[1]
