Banks are less important than ports

Less than two years ago Congress was up in arms about Dubai buying an interest in some of our seaports. The previous year the uproar was about China buying Unocal. Why are they now silent about all the investments into our financial companies being made by Singapore, Kuwait, etc.?

Perhaps it's because of the lobbying of the U.S.-Emirates Alliance, a lobbying effort of the U.A.E. Or, maybe it's because the financial industry gave 32 times as much money to congressional campaigns in 2006 than did sea-transport companies.
