In addition to the factors described in the article, in the United States there is an additional and very real incentive to work "bullshit jobs" and that is that health insurance is tied to employment (far less expensive when purchase through or by your employer). Unexpected healthcare costs are one of the leading causes of personal bankruptcy, so this creates an unnecessary incentive to have a job.
Sorry if this question sounds dumb to US people, but wasn't "obamacare" supposed to fix exactly that?
