Frankly, I think
you're out of touch. I don't have a trust fund, and I acknowledge that there are people to whom my statements do not apply. I pretty explicitly said I was talking about the common case, which is not "unemployed and looking for a $10/hour job." You are talking about a very specific situation which is much poorer than average, statistically speaking.
Anyway, though, I suggested that $5000 car (which is a once-a-decade splurge) as a convenience. I explicitly said that. Many people, including me, have made do with public transportation or lousy cars (at a $10/hour job, yes — this is from experience). I still maintain that there are much cheaper options than the "plasma TV, high-speed Internet, cell service" lifestyle that was under discussion here. For example, you definitely don't need TV, and if you're looking fo a job and really need a phone, you can get a prepaid one for like $10 without committing to an expensive plan.
And it is simply not my experience, nor that of anyone I know (who range from unemployed to poorly employed to very gainfully employed) that hiring managers will not wait a few minutes for you to call back. Has that actually happened to you a lot? I believe it happens sometimes, but again, I don't believe that is the common case.
If you really work for somebody that horrible for $9.10 an hour, I would urge you to seek alternative employment at someplace like Subway, Albertsons or Starbucks, where they have similar compensation and in my experience they tend to treat people better than that.
Also — and I mean this sincerely, not to be snarky — I would suggest you look at how you approach people, because frankly you come across as rather hostile and negative. I understand you find your situation frustrating, but you need to try to stay positive. That will impact your chances of landing a job much more severely than your ability to answer an email within 30 seconds of it being sent.
Anyway, best of luck to you, whether you agree or not.
