I can suggest a few trades that will benefit.

Locked up at home as the family unit for the first time in......ever?
Kids, parents, animals all in close proximity for 1-3 months.

Lawyers for d.i.v.o.r.c.e.
Drug manufacturers - i am going to suggest mogadon may take a lift and calpol will become an epidemic.
Delivery drivers in bio suites will be largely free to drive like lunatic bananas and park all over the road and pavement (god save them from catching it and us from them)
Punchbag vendors as people look to alternative ways of working out the frustratrion.

I have already heard from one of home-working ladies that the keep-fit she is doing will now be run on line. The trainer has taken a free account with 8x8 (video conference) and is using it to run the class with people joining in over the interweb. I am told you can all attach a suitable pulse tracking thing and it shows up on a scoreboard. Just what we need. People having a heart attack at home whilst all the beds are in use!

May we live in berserk times.

Everyone loves a Morgan. Even me, unless it's broken again.
