It's not a symptom of the belief that you should feel lucky to have a job. We're talking about the same country where people who go to college expect jobs to be handed to them.
Instead, it's a complex cause rooted in a country built on entrepreneurship and a strong belief in the "free market" (whatever that means). This is why it's not regulated by any government (federal, state, or local). The US has a lot of factors that lead to its vacation policy, but, "You should feel lucky to have a job" is not one of them--that sentiment is a more recent attitude.
