Oh no I'm fully aware of that. That's because they are treated very unfairly by the system and our minimum wage is way to low. I think if someone works a full time job they deserve to earn a living wage that keeps them above the poverty line. Im not calling poor people lazy or anything that makes me sick actually.
@PetersSmith: At full employment, there should be no underemployment as well, I believe, since the productive capacity of the economy is fully utilised. (It is not considered underemployment if it's voluntary.)
