The point I got from his post was that recently graduated and unemployed kids should stop waiting to be offered jobs that obviously don't exist anymore, and bring out the entrepreneurial spirit that made this country great (a long time ago).

The point is not to mop floors for $20, but to create a website (essentially a business) that solves somebody else's pain. That is the essential idea. Find a pain, fix it, charge enough to make a profit and move on to the next pain point that needs fixing.
