Gotta disagree with you there. If they didn't and congress tried to get us to do it then we would finally have enough people wake up when their taxes went through the roof and vote the bastages out.
Your thread title implies that you have a problem with foreign nations investing the dollars they earn from free trade.
But I think that your real concern is Congress can't balance the budget. If this is your concern, it's a valid one.
If your concern is that foreigners are wisely investing dollars they earn from free trade, that's an entirely different concern. We would need some data on foreign ownership of real estate and foreign investment in US corporations to get the real magnitude of the issue on the table.
Which one of the above is your concen?
