It's a meme designed to express dissatisfaction with income equality and the desire to fix it. What isn't clear to me is what qualifies as "rich". Because a US based entry-level fast food worker is at the 50th percentile of richest people in the world by income, after accounting for cost of living and other regional inequality.
It's also pretty clear from studies that everyone in the top 30% of the richest in the world will need to give up a lot of our privileges if we're going to address climate change, and I don't think people realise how rich they actually are. https://wid.world/income-comparator/ uses some of the latest research to help you find out, it's definitely worth a look.
