Spreading it around rewards an orthogonal group that did nothing to create the productive output and will siphon off it like a parasite.
Spreading it around is inherently a worse way to decide where value should flow through a society; especially one as culturally diverse (ie, filled with many self-interested constituencies) as here in the US.
[edit: So sad that on a site dedicated to the entrepreneur, arguments that promote entrepreneurship and rewarding good choices and hard work are moderated into the dirt..]
And I don't think you have to give up business or innovation to get it. If your Scandinavian startup becomes the next Mojang, you're still going to be fabulously wealthy, so I don't feel at all disincentivized by the distant possibility that I'll have to fork over a percentage of my hypothetical future millions (I'm certainly not going to move back to Texas just for that). There are more successful companies per capita than you'd expect (certainly more than most American states), and the economy generally still runs on a market basis, there's just a little more sharing of the wealth.
Notice that I mentioned cultural diversity. There is a reason that Scandanavia can manage with a more socialistic government. The gene/meme pool is far less diverse and evolutionarily created reinforcement of good communal practices are already present. A thousand years ago and beyond, if you didn't grok cooperation and thoughtful planning, you starved and died come winter.
Scandanavia is like a petri dish with a thriving germ culture that has had very little exposure to many other competing germ cultures. It's easy to point to that little petri dish and say, "See how well this culture thrives?"
We don't have that luxury in the USA. Here, we deal with many self-interested gene/meme contributors who are more self-interested than community-interested. If we implemented the government and laws of Norway here in the US tomorrow, we would collapse. Too many here would take the free government support as a right and live off of it until the whole system failed.
And you Sir are a prime example. In fact, you do everything you can to spread such memes in the society. The irony of that sentence amuses me.
In the end, though, those little petri dish cultures are not where the action is in the world. One merely needs to look at the last 200 years of innovation and invention to have the overwhelming impression that the USA method for technological and economic progress is to be admired and pursued. It's a damned shame that so many people here are hell bent on taking us backward to a one-size-fits-all European style socialistic government.
