This is how I think of income inequality: If I am determined to change my economic status and I consistently put in the diligence and hard work to make that happen, how much is stacked against me to prevent me from accomplishing my goal within a reasonable time relative to my starting point. This is the root cause of income inequality.
Interesting read with some important talking points, but overall, another extreme piece on income inequality. Just to point out one of such extremes, the nurse would be equivalent to an employee in a startup or a company, not the founder or startup as a whole. Now considering the cost of healthcare and the few people that can really afford it, by the reasoning here, the nurse is also contributing to income inequality.
I also do think that the analysis that results from using the $129,000 value for a human life is another extreme. First, per market basis the value of a human life is dependent on their market value. For one, I can hardly think that the value of an African human life will be valued the same as an American human life by majority of Americans. But even if we assume that the value of life is uniform, the question becomes how many lives do people really affect with their jobs. Interestingly, the higher the impact (with respect to cost) you can have with your job, the lower the number of people you can actually affect or the farther away you are from them. Logically, even if you can only offer very limited value to a vast amount of people, it reasonable to expect that the accruing value could possibly be higher than the value of a few really important impact.
