It is true the government can redistribute funds into investment. It’s also true if the citizens don’t make any money, the government will have little to tax and redistribute.
That’s only true if there is a balanced budget law that said government needs to comply with. The government here in the USA has been redistributing money here for ages that is not tied to taxation.
USA is a special case, with the dominant global reserve currency and military force, we have the special privilege of printing money that everyone needs. The UK hasn't been that since Bretton Woods
I don’t see how this is a privilege. It it nothing short of theft of money from taxpayers. People are saddled with the debt of others before they are even born.
