To butcher a famous poem, it's better to have hired and lost than never to have hired at all. Restrictions on letting go of enployees mean that companies are afraid to hire. They double check and triple check, they reject everyone they feel even the tiniest bit suspicious of, they try to protect themselves with ultra long probation periods, etc.

I don't know about the US, but I spent 4.5 months trying to get a new job here in the EU as a senior dev. Everyone tells me that was quick.
