So there was President Obama, giving his bazillionth speech on health care, droning yet again that “now is the hour when we must seize the moment,” the same moment he’s been seizing every day of the week for the past year, only this time his genius photo-op guys thought it would look good to have him surrounded by men in white coats.

If the IMF is correct (a big if), China will be the planet's No.1 economy by 2016. That means whoever's elected in November next year will be the last president of the United States to preside over the world's dominant economic power.

While Barack Obama was making his latest pitch for a brand new, even more unsustainable entitlement at the health care 'summit,' thousands of Greeks took to the streets to riot. An enterprising cable network might have shown the two scenes on a continuous split-screen - because they're part of the same story. It's just that Greece is a little further along in the plot: They're at the point where the canoe is about to plunge over the falls. America is further upstream and can still pull for shore, but has decided, instead, that what it needs to do is catch up with the Greek canoe.

In 1897, troops from the greatest empire the world had ever seen marched down London’s mall for Queen Victoria’s diamond jubilee. Seventy years later, Britain had government health care, a government-owned car industry, massive government housing, and it was a shriveled high-unemployment socialist basket-case living off the dwindling cultural capital of its glorious past. In 1945, America emerged from the Second World War as the preeminent power on earth. Seventy years later . . . Let’s not go there.

The trouble with the social-democratic state is that, when government does too much, nobody else does much of anything.

What can Americans learn from the Olympics spectacle? According to the IMF, China will succeed America as the dominant economic power in the course of the next presidential term, so Howard Fineman, editorial director of the Huffington Post and MSNBC mainstay, was anxious to pick up tips. 'Brits long ago lost their empire,' he tweeted, 'but overall show us how to lose global power gracefully.' So there's that.

In the Western world, countries that were once the crucible of freedom are slipping remorselessly into a thinly disguised serfdom in which an ever higher proportion of your assets are annexed by the state as superlandlord. Big government is where nations go to die - not in Keynes' 'long run,' but sooner than you think.
