> No, I'm saying that there's always going to be some level of wealth that's difficult to achieve. Social mobility isn’t really about the “difficulty” of achieving any particular level of wealth. It’s about how many people who start at some lower level of wealth achieve some higher level of wealth. Income inequality is also not really about the “difficulty” of something. It’s not exactly “difficult” to inherit the wealth of the wealthiest person in the world, either, but it obviously can only happen to a very small number of people in the world.
