It's good for people to have a job, even if they are not the best one for that job. It helps keep the framework of society together. Ideally, people could exercise their true talent and get paid but it's not always easy to get paid for what you like to do. Like Jim Rohn says - if all you get from your job is a paycheck, you are underpaid. It's a series of checks and balances - no perfect job is out there - it's up to you to make the best of it.
I'm pretty sure he was serious. Large masses of unemployed people aren't good news for anyone. While having a dream job beats having a lousy job, having a lousy job is a heck of a lot better than the hopelessness and helplessness that comes from not being able to get a job.
