I said something similar to my eldest recently, but in reverse. Now is when we discover all the non-jobs that were out there, simply doing unnecessary but nice-to-have stuff that when it comes to a national emergency, have had their true lack of value exposed for all to see. Example I use is nail bars. No real need for them, no significant barriers to entry, no real value to the economy other than it offers something others were willing to pay for but could just as easily do without.
