End stage capitalism is where we're headed, where the rich have gamed the system to the point they aren't taxed and the rest of us fund everything. They've practically captured our government with "Citizens United" and the "Patriot Act." It's exacerbated since the 1970's. Even Warren Buffet acknowledged that his secretary pays more per capita, than he does. So if we went back to the tax rates under Eisenhower, or better yet 90% above 1 million in personal income, then capitalism might be viable. But that isn't what happened. And we're headed back towards kings controlling countries and the serfs they own; with the current wealth levels of oligarchs and CEO pay disparity vs their employees. We can't even get reasonable health care and costs under control in "the richest country on earth." Medical bankruptcy is a real thing where most citizens don't even have $400 in emergency funds.

So NO, capitalism is not the best example. Only people lucky enough not to have been destroyed by it yet, might think it's still viable.
