The case for liberty has never been more clear. There are now about a hundred countries that are (true, flawed, and hybrid) democracies with (overly) regulated capitalist economies with safety nets. Actual socialism is a dead issue. The new game is social democracy.
Are these countries perfect? No. Are they better than what they had a century ago, or even fifty years ago? Heck, yeah.
Each one of these countries -- from New Zealand, to Denmark, to Singapore and Hong Kong -- each place makes a separate case for economic and personal liberty, and the more deeply we look at each one, the more we see that it does.
I think it behooves us to study these places, and learn from their failures and successes. Libertarians have the ability to go beyond left and right here, and look at actual liberty in these places, so we can make our case to Americans even more. The world has changed, and the facts are with us.
