The boom industries in a time of crisis

It's interesting to see what are the boom industries during the COVID-19 crisis:
Grocery stores and supermarkets (logical, given the downturn in restaurant meals), pharmacies, dollar stores, delivery services, medical supply makers, cleaning and security services, and IT firms that enable temote work are all currently hiring extra personnel. All quite logical, I guess.
And then one that is not quite so expected: flour and sugar mills, as home baking takes off in an unprecedented way. And, apparently, astrologers.
