Slave wages or not, rich are getting richer and poor people poorer (inflation taken into account). There is nothing to add.
True, but Musk, Bezos and Zuckerberg are still outliers. For example, Warren Buffet's net worth stood at $60bn in 2013 and $120bn in 2023. Adjusted for a total CPI inflation of around 30% over this decade, Buffett's real (inflation-adjusted) net worth rose by "only" 53%.

The truth is that the net worth of most of the ultra-rich is tied to how their companies are doing, which is heavily dependent on the specific industry. Slim's net worth shot up during the 90s and 00s due to the cellphone boom, but has barely kept up with inflation rates since 2012 because his sector (cellphone and telecommunication services) has become stagnant, with low margins and low growth.
Musk, Bezos and Zuckerberg happen to be owners of companies in the industries which have grown the most in recent years.
