But not just quantity of work, but also quality; the US is infamous for having millions of bullshit jobs with bad pay, poor working conditions, and no future prospects.

This was pretty bad with sub-minimum wage pay jobs (restaurant / bar industry, tipping culture) and people having to work multiple jobs to make ends meet, but it's gotten worse with the race-to-the-bottom gig economy, 0-hour contracts, prison labor/slavery, no changes in minimum wage or worker rights, de-unionization / union discouragement, etc.
