Scott Adams, creator of Dilbert, says that capitalism is out-of-date due to crooks using technology to steal.
…capitalism had a good run, but it will soon be done. Socialism will be too expensive to maintain as the world economies slow, and communism won't be making a comeback. The economies of the future will be something new.
Capitalism was conceived before the Internet, and before the gears of commerce became computerized. The system could absorb a lot of con artists because they didn't have the ability to steal fast enough to cripple the system. As you know, that has changed. Crooks in expensive suits now have the ability to swindle trillions, collectively, thanks to the efficiency of the system. And idiots in expensive suits can do even more damage.
The economy is now too complicated for even the regulators to know when a con or a huge mistake is happening. The balance of power has swung to the crooks and the market manipulators. Even if we could regulate away these problems, it's already too late. There isn't enough money left to support the planet under the current social systems, at least not when the boomers start retiring and unemployment starts climbing.
