Here is a very sad and frightening fact: the owner class can actually restructure "the economy" (whatever that is) to revolve entirely around AI consuming AI, and machines using machines.
Most people assume that "the economy" can only ever be based on human consumption, and therefore humans have to have an income in order for "the economy" to exist. This assumption is erroneous; billions of monetary transactions are done every day by companies with no product, no service, and no employees. These are economically valid, even though barely any humans consume or produce anything. The owning class just manages to convert those virtual transactions to "actual" money, and buy products and services because we already produce more than we consume.
It is more than frightening, but "the economy" (whatever that is nowadays) can run without many humans in the loop. AI consuming AI, phantom companies doing transactions with other phantom companies, machines working for machines.
