If the surplus is handed to the workers then they typically consume it and consume cheap goods and services (like taking vacations), which will tend to be imported and thus eradicate the surplus.

If the surplus is handled by industrialists it will be invested, thus turning to wages, then imports.

If the surplus is going to remain as surplus it needs to be kept as foreign assets, thus handled by financial gamblers. And what assets are more profitable in the short run for the financial gambler then dodgy assets?
