What a lot of handwringing over nothing. Nothing is likely to change. Chinese owners still have to adhere to American laws when operating in this country. If it bothers you that bad, Chase can set up a nice little savings account for your 100 bucks over at Morgan Stanley and probably for less fees. 
And the Chinese don't invest in shit to screw it up, they don't like throwing money away any more than anyone else does. Foreign investor control may have lots of problems, but suicidal financial impulses aren't among them.
