The overwhelming majority of people have whatever job they can get. They don't get to be selective, because they have bills, and kids, and rent to pay.
The overwhelming majority of people don't live in the US. In Europe, you have access to free healthcare, unemployment and education. It's not a silver bullet, but it significantly reduced your vulnerability to eating shit from your current employer.
Why the US doesn't value safety nets and collective action is beyond me.
Continuing that line of reasoning, the overwhelming majority of people don't live in Europe either. They live in India, China, Africa, South America where free healthcare, unemployment, and education are not always available.
This reminds me of this article [0] where more than 50% of world population lives inside of the circle compared to outside; which is fascinating as it covers only 20% of land-area.
Unemployment benefits are bit tough sell when you don't have enough savings and you don't get it for quite a while when you leave on your own... And educations isn't always that simple matter either.
