North Korea is a totalitarian state in which people lack far more than economic freedom. They have no real control of who leaders are nor any of the constitutions rights that we have. They can't even express themselves without fear of reprisal. That is not socialism. It's totalitarianism.
Taxes are based on income or wealth which doesn't have much relationship to what makes people happy. This is why people in countries with far less wealth are happier than those in wealthier countries as long as basic needs are met.
The claim that people in more socialist countries such as Denmark are happier than those in capitalist countries such as the US is based on the fact that people that feel more secure are happier than those that feel less secure.
Alright, send me your money immediately then. Let's see you live your values.
Again, I find it far more likely that Denmark being above US in the heritage index is far more likely story as the success of Denmark.
I also believe you have produced nothing in your life, but are just a leech. Of course economic freedom doesn't matter to you.
Although money doesn't buy happiness, it buys everything else which is a comfort in your misery.
It's hard to believe you can be happy when you don't have money to buy your son a new bicycle or Xbox console. You can't buy your wife new clothes or afford to go to the hair dressers and you have to use a 10 year old car that breaks down once a month.
You certainly can because happiness is a state of mind. If every one in your neighborhood has an Xbox, new bikes, and new clothes, you might be unhappy if you couldn't provide these. However if such items were rare in your neighborhood, you would probably be happy providing last years Xbox, clothes and bikes.
I've found from personal experience that giving my family what money doesn't buy, my time, attention, and love creates far more happiness than Xboxs, bikes, and new clothes.
