It is virtually impossible to survive in the United States without employment.
I don’t think the “coercion” perspective is the most convincing argument, personally: but there really isn’t much of an alternative to employment. The fact that the US has starving children speaks to how little of a social safety net we actually have.
I guess while I wouldn’t personally use “coercion” in a debate about this stuff, it’s also somewhat of a reasonable argument when you consider the alternatives. It’s just very ... meta.
