Treating all features as if they are all problems is not a correct way of thinking.
Clearly, some of the features have just made the financial market more efficient, such as lowering interest rates and reducing some differentials.
Those should be welcomed and fully embraced as positives things, as opposed to "problems".
International financial flows, similar to and perhaps more than international trade, is likely to grow at a more rapid speed than GDP growth, especially as international barriers diminish over time and financial markets are further integrated.
That should not be a problem.
