> there are too many jobs that do not pay enough to live on.
I know this is argued as a reason for high unemployment on the internet, but it does not match my experience in the real world at all. Having a job that pays a little is more income than no job at all. People stuck with low paying jobs often have multiple jobs as a result.
You seem to be confused about the point people are making. The point is that from about 1945 until around 2000 in the USA there really wasn't such a thing as "a job that doesn't pay enough to live on".
People owned houses and cars by working at grocery stores. A single income from any white collar job supported a stay-at-home spouse. Teenagers bought cars by working part time. College kids paid their tuition and living expenses for the full year by working summers.
That today's below-poverty-line job still leaves someone better off than being completely destitute is beside the point.
Many jobs require additional expenses: car, commute, babysitting, living in expensive city, no insurance for work related injuries...
So "not enough to live on" often means, it does not even pay job related expenses! Employees are subsidizing their employers!
My partner had a good job offer, but is at home! Buying extra car, petrol, child care... We would loose 150euro a month...
