Are you assuming that a private water company would sell you dirty water?
We already know that prior to the EPA (and even after in certain instances -- hence the Super Fund) corporations don;t care what they do to our groundwater and air... UNLESS government makes sure they fly right.
We also know airlines are required to inspect and repair their planes in accordance with government safety.
If you work in a place where you're not sucking in asbestos, it's because government controls that.
If you eat untainted food, it's because of the FDA...if your pharmaceuticals are safe, it's because of the FDA... if one owner doesn't control all media in your market, it's because government makes sure that there aren't monopolies on information.
if your milk is priced in accordance with market forces and not because of a deal made by a bunch of corporations to price gauge, it's because of federal anti-trust laws.
If you had a government backed student loan like i did.
If you went to a State University like I did, it got help from government.
If you had a disaster happen where you live, like we did here on 9.11, you benefitted from FEMA.
If you have ever driven from NY to California or Maine to Florida or any other configuration, you rode on goverment roads.
If you rode on mass transit, it came from government.
If you were educated in public schools, it came from government.
If you ever worked for a company that had a government contract, you benefitted from our govt.
If you ever worked for the goverment...well, that goes without saying.
If you ever had to sue someone in court, you benefitted from government.
If you have taken a plane at any time since 2001, you have benefitted from the TSA and DHS.
If you live someplace, like I do, where they thwarted a terrorist attack, then you benefitted from government.
And no, the taxes they take from me wouldn't have covered all of that.
