Well, I am a less than $5 engineer.
The only difference between the $50 engineer and $5 engineer is location, and the 100 years more of industry history behind the $50 engineer.
I think the $50 engineers are better generally, because of that history, but maybe the difference is not as big as in salary. But you can live a good life in China as a $5 engineer. So, it is about location.
Many many $5 engineer are well educated. But that is not because they want to, that is because they have to. Someone said in a post that as a engineer, he earns only $10000 more than a bus driver in US. But in China, even in Shanghai, a big city, an engineer earns 2 or 3 times more than a bus driver. Life will be very hard if you are an assembly worker in Shanghai, so you have to get a high degree to become an engineer. I am now on a trip in Germany. I found that being a worker here can also live a good, maybe not rich life here. So, that is the difference.
Still, I think $50 engineers are better, but maybe $25 is the proper price. Just a joke!
