the thing is that it doesn't even inconvenience them. it's a net gain for them as well. (they just haven't understood that yet)

consumerism is in decline because people have less money. if people consume less, companies can't sell products, so they have less revenue, so the company's worth less. rich people hold all their wealth as assets of some companies (or apartments that they rent out). if consumers have no money, these assets become less valuable as a result. the only way to keep these assets valuable is to stimulate consumerism, which can only happen if the people have money that they can spend.

taxing the rich might superficially appear as if it would annoy the rich, but actually the opposite will happen. if you tax the rich, the money goes to the people, who spend it by buying products, and so the companies (and therefore the rich) recover that money. as long as that cycle keeps spinning, there's revenue to be made, and companies and assets are worth something. the wealth of a country is measured in its productive force; if there's no consumption of products, companies and factories decline and crumble and the productive force diminishes. It is only as long as people continue to consume products that new products will continue to be produced, which means that the factories stay maintained and functional.
