Task of the raider

The task (of a bidder; raider ) is to identify asset that not used efficiently, acquire it, make it efficient, and than realise it at competitive price on the market.

Where the wealth is?

The level of gross foreign claims on U.S. assets is approaching $14 trillion, about 25 percent of U.S. wealth and perhaps 10 percent of global wealth. Eventually, foreign investors would become reluctant to own, say, the bulk of U.S. assets or to have the majority of their wealth holdings invested in one country. However, we are far from such limits for two reasons.
Followign that logic, the USA is home for the 40% of global wealth.
