So time and again, we see the decline of public services accompanied by the rise of private workarounds for the wealthy.

Is crime a problem? Well, rather than pay for better policing, move to a gated community with private security guards!

Are public schools failing? Well, superb private schools have spaces for a mere $40,000 per child per year.

Public libraries closing branches and cutting hours? Well, buy your own books and magazines!

Are public parks — even our awesome national parks, dubbed “America’s best idea” and the quintessential “public good” — suffering from budget cuts? Don’t whine. Just buy a weekend home in the country!

Public playgrounds and tennis courts decrepit? Never mind — just join a private tennis club!

I’m used to seeing this mind-set in developing countries like Chad or Pakistan, where the feudal rich make do behind high walls topped with shards of glass; increasingly, I see it in our country.
