Whenever I hear "the government ruins everything" I know that I'm hearing ideology, not reality.
The people saying such things take so many of the regulations, which make this country run smoothly, for granted.
Whenever I hear "the government makes this country run smoothly", I know that I'm hearing ideology, not reality. The government is by its very nature and definition an institution of criminals that accomplishes everything it does by force and coercion. In a democratic nation, just because 51% of the population chooses something, it does not mean it is justified to FORCE the other 49% into doing it. Likewise, the 51% majority likely will not even get what they vote for anyway, as is seen with the current and previous American administrations. You may remember that GW Bush campaigned on a non-interventionist foreign policy.
All of the agencies you have listed have nothing to do with the quality of food, worker safety, air travel, highway safety, and building codes - those things are all improved only by the actions of free individuals on the market. While companies may be compelled by government "standards", the real driving force behind any increase of quality is due to competition. Company A, no matter how large must, must maintain a certain level of quality if it does not want to risk losing market share to smaller, better companies in the same sector. The belief that without government constraints, all production would be rubbish or food poisonous, etc. is ludicrous. On the contrary, look at any country that has had increased controls and you will see less production at a lower quality, along with a worse standard of living.
In a free market, no company can escape from competition. Coercive monopolies are not possible without government policy. Without the force of government, no company has the power to force anyone and can always be out maneuvered.
