There’s only one conclusion to draw from this: American employers no longer buy into the concept that wages should reflect a worker’s productivity and efficiency. Instead, they throw in occasional flashy bonuses that bear no reflection to the reality of hard work.
Well, you started out with an erroneous assumption, that being that the only variable in a worker’s pay is their productivity. And then you double down on the error by expecting a 1:1 relationship between productivity and wage.
Neither of those have ever been the case nor a reasonable expectation. The largest variable in wage has always been the availability of workers in the skill bracket the employer wishes to hire. To illustrate that with an absurd example, if there were only a few hundred qualified burger-flippers in the world, but 1000 qualified coders competing for every programming job, the burger-flippers would out-earn the coders.
Further, you implicitly assume in your tome that all workers in a given genre produce at the same rate. Not so. We have plenty of MBA’s, but MBA’s working in marketing at some mid sized company might earn 100K, while an MBA working on Wall Street might earn 10X that in bonuses, IF they produce profits for the company.
(Frighteningly, one of the only professions which works pretty much the way you want it to work for everyone is Wall Street. Pretty much all the traders get the same salary, based on years of tenure, but they then get a bonus based on how much profit their trades that year have brought into the company. Is the fix to your concern, then, to have an entire economy that operates like Wall Street?) :-)
Word to the wise: Make sure your core assumptions are factual before you write an essay.
