I think so. I made this statement during a discussion this weekend and my ultra-liberal friend was breathing fire before I went down the list of atrocities against women condoned by many other cultures. I told her to try being a woman in Iran, India, or any number of Asian countries and see how much she likes it.
It's a little arrogant to have this opinion, but my view is based on the system, not the people. Our system of government, our laws, our branches of government are superior to any other culture in the world. It's the people who get in and screw things up.
If you step back and look at what we offer, it's unmatched: freedom of speech, the press, religion, expression, due process, free lawyers, the right to a jury, the appellate system, the legislative process, checks and balances, anti-discrimination laws, the welfare system, anti-patient dumping laws (meaning if you show up at the ER with an emergency medical condition they have to treat you), protection of incapacitated people, property ownership, the free market, the educational opportunities, professional opportunities, leisure activities, sports, strong defense, solid infrastructure, fire and law enforcement, charitable entities, foreign aid for countries that suffer disasters, and the list goes on.
All of this isn't necessarily "culture," but it's all related IMO.
