Governments need taxes to help finance their operations. But in most cases, they overcharge their citizens, adding more burden to the economy in the long run. Overtaxation has always been an issue, especially in the US and some other countries. I believe that's why most people (especially young people) don't want to work these days. They want everything without having to pay anything in return. Well, their dreams will come true as AI will take control of everything.
So instead of humans being subject to slavery, it would be AI itself. The government will still be able to collect taxes from things that AI produces or helps create. Donald Trump's tariffs could work if they ultimately abolish the income tax. Not only that, but they will serve as a way to ramp up domestic production. Be aware that with the rising cost of living, comes increased criminality rates. Who knows what the future holds?
The "less government" movement came from that, because our taxes are not used efficiently. Just recently, Elon Musk, even though I dislike him, proved that there could be plenty of cuts that he can do to the government himself. It's clear that there are things that government needs to spend money on, but there are things they are wasting money on some other stuff as well. So we need to focus on how they could be doing a good job if they know what they are doing but most don't.
However, problem with less government is that, even if you let people take care of most, government still needs to handle some stuff, law, cops, military, even education to a point. And they can waste a lot of money on those too, which is corruption at its core.
