I personally view it as the Pareto principle at play.

If we were to equally distribute resources among the entire population, over time we would see those resources begin to bunch up into the top 20% of society due to superior abilities (intelligence, business instinct, skills, etc.)

As time continues, then resources continue to pile up at the top 20% of the initial 20, and so on, and so on...

I might be okay with that, if there was no possibility for ultra-wealth to be inherited from one generation to the next.

Make each generation work hard for their wealth, and you avoid the concentration of wealth that occurs because it is also a concentration of political power, at which point the sole purpose for that wealth and power is to accumulate more wealth and power and give their kids an insurmountable advantage over the next generation of kids.
