I hear sentiments like this a lot lately, and it feels short-sighted to me. COVID restrictions are not going to be around forever. There are financial, professional, social, and other costs that come with moving somewhere else.

For people who genuinely don't like it in $HCOL_AREA regardless of the pandemic, and see this as a way to get out permanently, then that's great, and they should do that. If it's more like "it's expensive here and I can't go out to my favorite bars/restaurants right now", the latter half of that situation should fix itself by next summer, and hopefully earlier in some fashion. Sure, that's a while to wait, but isn't much time when considering that an alternative is to uproot your entire life.
