> that's pretty much the only thing the US government does
Besides waging bloody, unnecessary war (War of 1812, Mexican War, Spanish American War, Vietnam War, Iraq War); instituting explicitly racist immigrating policies; waging a disastrous War on Drugs at home and abroad; instituting protectionist trade policies on behalf of rent-seeking corporations and unions; busting unions; interning thousands of innocent Japanese Americans; the mass expropriation from and relocation of thousands of Native Americans; and hundreds of less memorable abuses, not to mention its complicity with several of the ills you mentioned, yeah, sure, "pretty much the only thing" the US government has done has been protecting us from "the tyranny of private businesses".
I like how we're evaluating the USG of 2014 on the War of 1812, among other things.
I was involved in planning for a 200-year commemoration of the War of 1812. We invited the U.K. and Canada, amongst other nations, and they were glad to send representatives to the commemoration, despite the fact that the U.S. was at war with those 2 nations in 1812.
I was talking about domestic policy, which is the issue here. There is no doubt that the US government has done a lot of wrong, only much -- if not most -- of it has been done in the name of business. So your defense of Google (as a representative of private business) over the government, is that the government does a lot of bad when it's fighting on Google's side, and that it's not fighting against Google enough? Of course the government fights alongside capitalists most of the time, but the capitalists can do the same harm on their own (which they did when there was little government to stop them). The difference between American corporations and the American government, is that sometimes, when things get bad enough, the government turns against businesses, while the businesses themselves almost never do.
