Love it, but it has one problem. Your argument is basically that it's a free market.
So, assuming the market is bad and jobs are hard to find, is it then ok to work nights and weekends like the article describes? Or should there be some kind of limit to "slavery"?
If it's a free market and "jobs are hard to find", or in other words "the supply of quality employees is lower than the demand" then it's the perfect time to start a business. You can get a good deal hiring good people. You don't even need an awesome business strategy, just make reasonable, productive use of their talents and there's plenty of room for you to come out ahead.
To the extent it's hard to do this -- there aren't many talented, underutilized people floating around unable to find work -- that's the extent to which it's not actually hard to find a job.
