Free market refers to an economy where the government imposes few or no restrictions and regulations on buyers and sellers. In a free market, participants determine what products are produced, how, when and where they are made, to whom they are offered, and at what price—all based on supply and demand.
In the US, the majority of blockage to a truly free market comes from the government. They forbid producers from polluting, pricing below cost, or being a monopoly. In addition, they often require minimum safety standards, the disclosure of ingredients, licensing of certain professionals, and protection of original ideas, to name just a few. They even control the money supply to minimize the negative effects of natural economic expansion and contraction.
Some of these things may SEEM like a good idea. We all want the market to thrive, but time and time again it has been proven that the market thrives best, when it is left alone. When there is competition, consumers will choose the best available option for their goods and services needs. Factors such as time, distance, ease of use, customer service etc all effect companies well being in a buyer's market. When the government interferes with the market, buyers lose control. Here in the United States, there is a lot of favoritism for government sponsored programs that are supported by taxpayer dollars that would NOT survive in a free market.
The best example I can think of is USPS. Now, I don't know how your local postman treats you where you live, but I've gotten mail at 5 different addresses over the last 3 years. I can say with certainty that amongst the big 3 delivery services: UPS, FedEx, and USPS that USPS by far has the least reliability and the worst customer service. When I ship something with FedEx or UPS, it gets where it's going within the time frame I am quoted or in rare cases where it does not, I get a partial or full refund.
FedEx and UPS are typically a great deal cheaper than USPS, they have better customer service, a higher overall rating by consumers, a lower failure rate and from my experience, much nicer employees. So why does the USPS still exist? If overwhelmingly, the buyers PREFER other companies that provide the same services one would assume that they would take over the market. So why isn't that happening? Why do USPS employees continue to exist to complain about their employer (rightly so) on the internet?
Because they are supported by the US government. Because even though they have operated at a deficit for YEARS we continue to finance them out of our tax dollars. So, not only is the IRS stealing money out of my paycheck, they are stealing it to support a company that I purposefully DONT shop at due to rude employees and overall incompetence.
