GP said that in reference to rescinding a job offer after notice given, new job accepted, and old job left, not a 'layoff' exactly.

Personally, I think employment in the US should look more like it does in Europe. People rely on work to survive, and shouldn’t be fireable easily, and unemployment should cover at least 75% of your previous salary.

I am in Europe; here it is common to have a probation period. After this period it is less easy to fire someone, but during the period they can do pretty much anything. So if you happen to be switching jobs right in the middle of an economic crisis there is not much security. In addition, in my country you get your salary covered up to 80% if you pay for extra unemployment insurance. I was stupid and did not sign up for this earlier - and you have to be a member for 12 months to get the benefit. If you do not have unemployment insurance or have not been a member for 12 months, you get <900 USD per month (where I live this is not enough to make rent).
