There's actually way more 'abundance' around the Earth then 50 years ago, it's just spread out more evenly. For example, even in Cambodia there's a Rolls-Royce

There's actually way more 'abundance' around the Earth then 50 years ago, it's just spread out more evenly. For example, even in Cambodia there's a Rolls-Royce dealership now. And even the 50th percentile Cambodian household has the material wealth now of at least a 5th percentile US household. Those saying 'OK Boomer' are mostly just ignorant and/or frustrated because they expected to have even more wealth automatically, when that doesn't make sense anymore now that the entire world can effectively participate in the market.
