Before the 1980s layoffs were seen as a massive failure of the company and almost never happened to tenured employees unless the company was collapsing. Before we are all made to think this is normal and unavoidable behavior.
I wouldn't have nearly as many complaints about this mindset change if ones life (e.g. insurance) weren't still so deeply tied to who your current employer is.
I don't know what the best solution for the current healthcare clusterfuck in the US is, but I think disassociating health insurance from employer/employment is a great first step.
