Just reply in bolded, yes, many other countries have stock market, it's normal for them to make share or invest with economy over world.
Really ? I never knew that. I just thought only one stock market in USA that the whole world depend on.
For oil in Saudi Arabia, Saudi is our friend and there's nothing is wrong to import the oil, economy wouldn't growing without import the oil because our domestic oil is limited then we have import the oil to keep the track, for me, I support drill the oil, I had changed my mind after used to against on it and don't know about congress would work out with lift the restriction to drill the oil (offshore and AK), this restriction law was very old.
Some day Saudi Arabia oil will be burnt down in the future due to massive war - IMO. I noticed the war is growin' in the Middle East.
In case, if middle east, including Saudi refuse to give oil to us then we can buy oil from other countries, such as Canada, Mexico or somewhere in South America. OPEC is partly blamed on expensive oil price and I believe that OPEC made biggest mistake with oil price but some oil countries aren't member of OPEC.
