"The thing that's possible in America and arguably not possible in Europe is to just show someone the door on the spot."

It's only sort of possible in America. If you are laying people off (for economic reasons, not cause) then federal law requires 60 days notice. This is enforced civilly however, so if a company is going bankrupt they may ignore it because there will be no one left to sue.

An employee laid off that way will be eligible for unemployment benefits, which is a form of insurance payout, not public assistance. What we don't require is severance. Most companies that are not going away will do something like 1-2 weeks severance pay per year of service because they want people to not sabotage anything on the way out and for new employees to continue to be willing to work for them, but it's legal to just pay people for time worked and give them the boot.
