The problem of wealth inequality was predicted to occur within capitalism long ago by a man named Karl Marx. So compelling were his predictions that entire societies have been constructed (and overthrown) in attempt to create a system that is more fair. Russia and China are the two biggest failed experiments in trying to solve this problem. Karl Marx may have been wrong about communism, but he is most famous for being right about wealth inequality and capitalism.
What Karl Marx said about inequality is this: It happens because of the private ownership of the means of production. As long as the lifeblood of the economy, its vital resources, factories and technology are owned by a tiny group of individuals, as long as production is governed by the law of capital accumulation and not the needs of society as a whole, poverty, injustice and capitalist crisis will remain and ultimately grow. Workers produce everything; the ruling class produces nothing, yet the ruling class own everything.
Take for example your typical Tech corporation: Apple. Apple makes $1,865,306 of revenue per employee. The top senior software engineer gets paid around $222,550, which is a number that is far higher than the average salary of an apple employee.
What is evident is this: The people who do almost all of the work in apple (engineers) are only getting paid less than a fifth of the revenue they generate. Where does the rest of this revenue go?
It is used to increase the incomes of a few people who do much less or no work. C-level executives pad their salaries with a huge portion of this money. Tim Cook alone got 10.2 million in 2015 and that's not including stock options. While tim cook is a very capable individual, his salary indicates that his work output is equivalent to the work output of 50 engineers. Can a single human produce output equivalent to 50 engineers? I would argue no.
The rest of the money is either distributed as dividends or reinvested back into the company in the form of infrastructure improvements or just money in the bank. Who directly benefits from this? The Shareholders or in karl marx's words: The people who own the means of production. These are the people attending davos. They are the real problem, it has nothing to do with AI.
