They don't dictate how government works; your elected officials do.
Don't be so naive.
They indirectly dictate how government works. How do you think those officials got elected? These corporations "donated" (for lack of a more appropriate word) money to their campaigns and/or PACs (and sometimes Super PACs) to help them get elected. More often than not those elected officials care more about the interests of their benefactors than they do about the interests of their constituents.
Ultimately, who steps in to the voting booth? Corporations? Special Interests? No the people do. And the people get what they voted for and get what they deserve.
Prove it. Some of our laws now involve corporations or service by a corporation. Some of our laws were brought in by lobbyists, who in turn work for corporations.
Tell me that they can't "influence" a law they helped write (or completely wrote themselves) and reap the benefits when it passes? -- Bresnan 30M/5M | CenturyLink 5M/896K MyWS[PnmIIX3@3.3G,8G RAM,2T+2T+1.5T HDDs,Win7] MyLaptop[Asus G53SX,32GB RAM,2x1TB HDD,Win7] WifeWS[C2D@2.4G,4G RAM,250G HDD,Win7] Router[PE1750,4G RAM,3x36G HDD,2xIntel Pro/1000+GT Quad Port,Gentoo]
Technically, the law is "implemented" by those that enforce the law. Legislation is made law by our elected officials. Draft legislation is typically written by staffers that are influenced by many sources, to include corporations.
