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.
Corrupt politicians are the main reason why the government is always in a deficit. It can collect as many taxes as it wants, but without proper money management, the economy won't be going anywhere. Young people are taking notice by steering away from work as much as possible. They want everything in hand without actually doing anything. And with innovative technologies such as AI, Blockchain, and Quantum Computing, who needs the "human touch" anymore?
I'm afraid companies and governments will continue to replace human workers with AI and robotics. It's the way of the future. Tariffs will probably replace the income tax in the long run. Only time will tell...
