The "get a second job" thing is ridiculous when most companies want you to work the same hours. It sure as heck ain't as easy as just telling them when you want to work.
What a lot of people seem to be missing is that full time positions are going away. It's so much better for a company to juggle two part timers instead. The benefits are not as expensive and they don't have to worry nearly as much about overtime or undertime. Where I work, they just split another full time position into part time.
As far as it being an entry level position, that would be fine except for the fact that many people with experience and/or degrees are having to take "entry level" part time jobs just to survive.
