The ruling class won’t give up wealth. They don’t pay taxes now, trying to take more will just make them leave or offshore. Increasing wages also means spending more, which increases prices by default. Tax cap elimination will just make people mad. Wealth taxes will make people move money offshore now (look at current millionaires and billionaires). Enforcing it would make them leave. Increasing immigration just kicks the problem down the road to when other countries stop having extra people to give. Immigration also comes with a slew of economic problems, such as keeping wages low and pressure on services. Given that most developed countries are in a demographic crunch now anyway, immigration would be an unacceptable net loss for most countries now anyway, especially if AI develops to take on lower/tier and even higher-tier jobs. A better healthcare system would only make more retirees, stressing the already Ponzi-like nature of social security and other pension systems. Taking more years from the working people isn’t optimal, but it’s one of the few options some countries have unless they want to destroy their pension systems.
