What's do you think about the article(How the Market Works-Supply and Demand)?

In my opinion, I can not agree with this opinion because this is a freedom sysetem about business. Actuallly,so many econmy crisis cause of freedom system in the world. Firstly, the government should be control the price is stable because the price is very importamt for the market very good work.However, thehe market determines are very important but they have defect. For example, if some dishonest businessman control the market for his own advantage, but the government just sit back and watch without going to the rescue. So, the recult is a lot of people will be lost a lot of money in the market. Most importantly, if the market determine price that is not a safe market because the market don't know how to deal with crisis.
