While I'd normally agree with the sentiment that "you're not poor because Elon Musk is rich," I'd caution people against getting over your skis. The K-shaped economy is real.
Governments are rapidly expanding public debt, not only to maintain a minimum standard of living for those in the lower half of that economy, but also to prevent a broader collapse in global demand. There are real and unsustainable economic asymmetries that have hardened over time, and policymakers continue to ignore them.
Those distortions are, in part, keeping people in the lower half of the K-shaped economy poorer than they otherwise would be. At the same time, many people in the upper half feel poorer than they should because of the very same economic dysfunction.
So don't dismiss the concerns of those on the lower half by saying they have no reason to complain. Their grievances are legitimate, even if they cannot always identify the underlying forces making housing, healthcare, education, and everyday necessities so unaffordable.
No one can predict the exact day of reckoning when these imbalances finally force a global rebalancing. But when it happens, many people who currently occupy the upper half of the K-shaped economy may suddenly find themselves in the lower half.
Thank you for summing up why people hate successful people: you think you're a loser because someone else made you a loser. The reason you believe this is that it's a lot more comforting than the truth: you're a loser despite the fact that amazing business leaders like Elon created hundreds of thousands of jobs and paid billions upon billions in taxes. In other words, the reason you're a loser is you, your shitty, envious attitude and the fact that you don't understand that the way to achieve what you want is to provide something other people want so they're willing to pay you for it.
