I totally didn't mean to derail a discussion of airlines into one about...crop subsidies?
My only point is that government has a role in the market, despite what Ayn Rand fan-bois might fantasize about (quick tip--you can spot the asshole in any crowd by asking them what book most influenced them. If it's Atlas Shrugged, back away slowly and GTFO). In the real world, there is a role for minimum standards and national policy. Their type and scope can be debated, but they have to exist in some form. Sometimes it's negative and sometimes positive. Sometimes people are hard over on "government is always the problem." Sometimes it actually is the problem, but if you think it's always the problem, I'd rather have a little paperwork over Somalia, 1996.
Government has actually played a huge role in the development of our economy, as far back as the 19th century. In 1765, A French general demanded interchangeability in the production of muskets. The U.S. Army, heavily influenced by French military thinking, founded two armories to work on this, the Springfield Armory in 1794 in Springfield, Massachusetts, and the Harper's Ferry Armory in 1798 at Harper's Ferry, Virginia. Development of interchangeable parts required a lot of research and development and many years. The goal was to be able to take ten muskets, disassemble them, mix all the parts together, then reassemble them and have them all work. This required development of special purpose machines, tools, jigs, and fixtures. Many of the workers who came out of these armories then took the knowledge they had learned to other industries. And of course then everyone knows of the government's role in terms of R&D of many industries during the 20th century with WWII, the Cold War, and the Space Program.
Also the banking system. We tried a wholly free banking system back in the latter 1900s but the result was lots of insecurity, fraud, constant localized bubbles and busts, and then culminating with the system almost blowing up. So we have a quasi-socialist (?) banking system today which is much more secure. On the other hand, the Federal Reserve flubbed it in response to the 1929 crash and caused the Great Depression and there are lots of examples of bad or excessive government regulation.
There is a saying I've seen attributed often to George Washington, although from what I understand that might be fake, but it is a good quote nonetheless IMO: "Government is like fire---a dangerous servant and a fearsome master." Fire has tremendous uses, but the larger it gets, the more difficult it is to control and the more closely it must be watched. It has an insatiable appetite and will consume and destroy everything if allowed.
