At risk of sounding simplistic, there's a reason why we live on a planet with somewhere around a hundred-eighty countries or so and not live on a planet with no countries, but with one huge central authority in charge. Because we have different populations, people's, cultures, values and everything else all over the planet. And what works in one country or even in a block of countries, might not work somewhere else with a completely different economy, with different resources, responsibilities, threats, populations and everything else.
My point is that U.S. Senator Bernie Sanders and his supporters, the social democratic-left in America lets say, have a tendency to say, "this is how it's done in Europe with government doing so much for their people and everything else. It seems to work there and their people love it. Which is why should adopt that economic system here and do it the European way". Apparently unaware, or ignoring the obvious facts that Europe and the states there are completely different societies. That for one thing don't even have to worry about their own national defense, because America is responsible for it.
Americans tend to be rugged, individualist, free, wanting to be able to make their own decisions and live their own lives. And in a lot of cases hate to have to take any public or even private charity. And when they do, they tend to see that as some type of failure and have let themselves and their families down. Europe is the complete opposite of that and if anything love taking public assistance from their government and would riot if the government were to cut their public assistance. And freak out about having to to pay for their own childcare out of their pocket and not taxes and actually have to take responsibility for themselves. And this is just an example of the culture differences.
Americans figured out a long time ago, well most of us did, our Socialists are still late to this dance, or still at the door, or not even there yet, perhaps sitting out the dance that there's a limit to what we want government to do for us. That instead we want to be free as possible to take care of us as much as possible. And then if we run into financial trouble, like being out of a job and just lost our savings as part of that result, then we would want to be able to take public assistance in the short-term until we can get ourselves back on our feet. With a good job that gives us the freedom to do those things.
That's the main difference from a liberal democracy, a liberal society the free society that the American Founding Fathers, the Founding Liberals wanted to create for America. And in the last two-hundred plus years we've worked as a country to improve our society so as many Americans as possible have that freedom to manage their own lives and Europe. Which is the opposite of that where they want to be taxed to the point where no one is completely free to take care of themselves. Because they believe when they move as a national unit, they move better with no one being too rich or poor and moving together.
So when Bernie Sanders Social Democrats say that, "Europe does it this way, so should we", they are comparing Massachusetts with Texas. What is done in Massachusetts, is not wanted in Texas and vice-versa. Both states have figured out an economic system and government that works for them. But that doesn't mean it will work for everyone in the country. Americans like being able to have the freedom to make their own decisions and you need your money in order to do that. Europeans at least in a lot of cases see that as selfish or materialistic and would freak out and even riot if their government's forced them to take responsibility over their own lives. Just some of the differences between America and Europe.
