There are plenty of high paying jobs (what's considered high pay is subjective) but there just aren't enough people to fill them skill wise. The reason why there aren't enough low paying jobs for people to snag two is because ANYONE has the skill to fill them so they go a lot quicker. It's not about JUST working harder, it's about developing/learning a skill that makes you eligible for higher paying wages.
The bolded issn't exactly true.

Some have attributed the more extended process to a mismatch between the requirements of the four million jobs available and the skills held by many of the 12 million unemployed. Thats probably true in a few high-skilled fields, like nursing or biotech, but for a large majority of positions where candidates are plentiful, the bigger problem seems to be a sort of hiring paralysis.
Theres a fear that the economy is going to go down again, so the message you get from C.F.O.s is to be careful about hiring someone, said John Sullivan, a management professor at San Francisco State University who runs a human resources consulting business. Theres this great fear of making a mistake, of wasting money in a tight economy.
As a result, employers are bringing in large numbers of candidates for interview after interview after interview. Data from Glassdoor.com, a site that collects information on hiring at different companies, shows that the average duration of the interview process at major companies like Starbucks, General Mills and Southwest Airlines has roughly doubled since 2010.
After they call you back after the sixth interview, theres a part of you that wants to say, Thats it, Im not going back, said Paul Sullivan, 43, an exasperated but cheerful video editor in Washington. But then you think, hey, maybe seven is my lucky number. And besides, if I dont go, theyll just eliminate me if something else comes up because theyll think I have an attitude problem.
As far as developing new skills, not everyone has a legitimate opportunity to do that, hence the problem. I can't spell it out any better than Broke Wave did in in this thread: http://www.the-coli.com/3805457-post66.html

It's fukking burger flipping. It is the most entry level work you can find. 
ELITE!?!? I'm not even talking about myself. I haven't brought up my compensation. My simple principle in all of this is that you earn the pay you able to convince someone to pay you.
