Learning how to make wise choices of employers is something you, as an employee, need to be more diligent about. You can spend all your time looking for a job that really interests you only to find out, after being hired, that the company is horrible to work for.
Sometimes you don’t have a choice. I took the first and only offer I got right after I graduated college, for fear of remaining unemployed. While it wasn’t the worst corporation to work for, I placed significant emphasis on benefits, growth structure, morale and overall approval when looking at companies for my next job.
