I have a pretty good theory on the point you raised. At least I think it's a pretty good theory. 🤪
Our govt, especially the dems, are very good at taxing and collecting money. What they're not good at is spending it.
They do the initial, easy work of identifying the problem, then in true, wasteful libtard fashion, they don't do anything to ensure the money they throw at the problem actually goes to what it's intended for. This allows them to use things like USAID as a giant slush fund, so naturally the dems are quite happy with that arrangement.
These other countries you're referring to are likely the Nordic countries who are super liberal. Not socialist by any stretch, just way far to the left. It's been a while since I did research into their tax rates, but they are very oppressive. Even by our liberal standards.
The difference, imo, is that these countries, unlike our leaders here, do not spend money like drunken frat boys with daddy's Amex card. These countries spend the money they take from their citizens wisely, because they are accountable to them, unlike our politicians here.
If we take Norway as an example, they're sitting on nearly $2 TRILLION (in US dollars) worth of oil fueled revenue for their pension fund. If they were to divide that up among their citizens, it would be about $340K per person. And all the while they're banning ICE vehicles in their country. The hypocrisy is off the scale.
One final point to make is scale. Maybe the Nordic countries systems would work in a small state here in the US (I nominate Minn. to be the guinea pig...) but certainly not when scaled up to a big state like Taxifornia, and absolutely not when scaled up for a country the size of ours.
If a politician came out with an approach to handle the scaling problem, I'd be very interested to hear their ideas. But just throwing good money out the window and convincing ourselves that we're the good guys because we allocate money to solve problems (that never get solved) as our politicians do, is not even close to the answer. We're deluding ourselves to the fact that we've just crossed the next $TRILLION threshold and are now $38 TRILLION in debt, which even an ill-informed dem should realize is not sustainable.
