Harness the power of greed and money.

Greed isn't inherently evil, but right now the wealth produced by society is simply used to produce more wealth, increasingly at the expense of society itself.

Basic changes to: campaign finance so politicians actually debate the issues; shortening the election cycle so they can focus on governing; tying CEO compensation to the lowest paid worker in the company (ratio of pay and stock options); earmarking funds meaning actually using those funds properly; etc.

A lot of the world has some of these already, but the point of capitalism isn't to let corporations do whatever they want, but to ensure a healthy economy where everyone can get ahead if they work hard.
