If an economy's working correctly, it certainly should be. The demand for goods/services and willingness to work for them is one of the few things that's basically fundamental to human nature. Of course we have all kinds of problems that make that inaccessible in an economy, or that artificially skew the ratio of one to the other (for better or for worse, depending on the person). First and foremost, that across the public/private spheres, a few people at the top have the entire economy by the throat.
It's definitely intentionally made difficult. It's not to say you can't just move around at jobs and stuff, but it definitely requires some tough measures and occasional high risks.
I don't like losers who can't make the smallest effort to improve their lives. If you think that's shit attitude, then you're destined to suffer. Enjoy your choices in life!
