The US lacks labor laws which means hiring people is a low risk activity since you can easily fire them. You can also work them for 60 hours a week and 52 weeks a year. The labor laws that do exist, for example in California, are about workers being able to switch companies versus them not losing their jobs. That means you can quit your job, start a startup, hire people, shut down the startup and then find another job with ease. When you need to give two months notice to just leave a job that whole process slows down significantly.
