And inheritance is one of the biggest source of inequalities hence why Piketty proposes a massive tax on inheritance to be redistributed equally as a universel basic inheritance to young people. There are hard core scientific papers behind it but this is a popularized article I have found: https://goodmenproject.com/featured-content/fairer-taxes-and-inheritance-for-all-the-economic-plans-of-star-economist-piketty/. Problem is inheritance is an extremely touchy topic, most people have the deeply rooted instinct to give everything to there children and can’t think rationally about it.
