That governments should control stock investments

For those of you that don't know, a stock is part of a company (or all of a company) that is owned by someone. Look here for more information: http://www.investopedia.com/university/stocks/stocks1.asp  The question we are asking: Should governments be controlling stock investments? For my purposes here today, I will be referring to America's government. Let me know if you disagree with this, and if you want a different country's government, or if you want to use several governments. Let me know in the next speech. Thanks.

I'll admit it from the start: I think that stock investments are important, and help both economy and businesses. However, I think that they should also be controlled. The definition of Control: the ​ability or ​power to ​decide or ​strongly ​influence the ​particular way in which something will ​happen or someone will ​behave. Control in this case is referring to how all investors directly influence all the investments that happen within their economy. Governments should definitely keep a watch over how investments are made, and how effective they are. There are lots of new investors that waste their money on ineffective investments, and does not help anyone. I'll give my contentions:

1. Governments that control their stock investments will have more effective businesses and a better economy.

2. Controlling the stocks gives them the ability to change the investments slightly to maximize profits for both the investor and the business itself, and stupid investments and investments that don't contribute anything can be vetoed and removed. 

Did you know that the US debt is about 19 trillion dollars currently? Did you also know that your debt is also about $60,000, assuming that all the debt were dispersed equally among all the people of the US? (US Debt Clock) With this debt, the United States definitely needs to keep watch over how they spend, and how to most effectively create money for themselves and their people. If our government spectated over our investments all the time, they could reduce our debt. Granted, we can't actually reduce all our debt by keeping watch over our stock investments, but it's a good start. There are lots of reasons that investments don't always go the way that we want them to. Assuming that some experienced or educated investor/official watches over the investments, then we can maximize profits. In the following paragraphs, I'm going to tell you why.

Don't you sometimes wish that there were a magical fairy godmother to always watch over you, and if you made a mistake, then they could fix it? That would be really helpful sometimes, don't you think? It would save us a lot of pain and embarrassment, too. Well, it's the same principle with investing. What if you're a new investor and you rush headstrong into investing? Lots of new investors always invest on things that they hear is going to be a ground breaking product, or is the new "Apple." Lots of newer investors make an unlucky guess, and end up losing lots of money. With our government watching, we could prevent this a lot more often. There are lots of other things that an unfortunate investor might end up doing.

They only learned by trial and error. If the government watches over these inexperienced investors, and even the more experienced ones, then they could potentially stop all these mistakes. 

Thanks for your time and consideration, judges and debater.
