One word answers: Lawyers.
US is so laden with regulations, lawsuits, bureaucratic red tape, etc. A company has to worry about the legal costs to build, hire, fire, speak, write, repair, and so on. All for our “protection”. Granted, some regs are necessary. But enough is enough and too much is too much.
Basically, government has figured out how to get it’s piece of the pie, and keeps wanting more.
Pretty much like the unions.
