I've noticed a number of jobs are now paying minimum wage for semi skilled labour, or even experience. I've seen jobs like full time overnight hotel desk clerk requiring 5 years of experience offering minimum wage. Front line tech support, which back in 2001 paid $13-18 an hour at many places now pays minimum wage.
As jobs become automated (like accounting), warehouse, order taking, manufacturing, welding, you're going to see a larger labour pool and a smaller job market. some of these jobs may be mundane but they still need to be done.
