"Are the elite wealthy hurting the US economy by purchasing stocks from outsourced companies."
The thing that hurts the US economy the most is heavy regulations. The more regulations you place on businesses the less likely a business is going to pop up. Not only that but those who manage to survive tend to become predatory towards competition and their own customers! Look at all the backlash from Walmart, people love to hate Walmart. When the company first started it had some of the lowest prices, now they don't even care about low prices because they have essentially snuffed out all the competition and just sell the same garbage for the usual prices. But I digress..
Many businesses in the US have moved out of country because operating within the US has become counter productive to making a profit. Which is the whole point in business. But I am not talking about greedy corporations. If you are forced to pay for benefits to your employees as well as make sure everyone is licensed and insured, your over head becomes WAY too much. But if you can move to a foreign country and cut your overhead in half or even more, then it becomes appealing and this is what has happened to almost every business in the US.
The backlash of companies moving to foreign countries is that they make those country wealthy. They employ the locals providing them jobs. The US loses out on jobs. Fewer jobs means less people buying stuff. Less people buying stuff inside the US means a slowing economy. So then the stupid politicians seeing tax revenue dropping off so they raise taxes on businesses. This causes more over head for these businesses so they either go bankrupt or they move out of the country. It is a snow ball effect CAUSED by the government.
To save this system we need to deregulate. (I know people hate that concept) and we need to get rid of the FED. The fed is part of the problem because they artificially lower interest rates and keep them low which causes people to go into debt. It doesn't allow for companies to save or invest which would lead to research and development. So companies struggle to innovate.
This whole economy is being strangled by the government and the political leaders.
