how ironic that your playground conversation has actually come true. although it isn't mexico, but rather it is china. the usa is indeed "owned" by china right now. today. it has already happened. who do you think bought up all that us gov't debt, so that we could fund all those multi-billion dollar bail-outs, obamacare, and the record federal budget deficit we now have? if you said China, you guessed correctly. and the record unemployment we have now is due almost exclusively to manufacturing job losses. where do you think all that manufacturing (and the many billions of dollars associated with that) went to? Yes, the same place all your shiny Apple products are made. China. And as the owner of all our debt, who do you think we pay tens of billions of dollars in loan interest to, every year? Yes, China.
China is the new world super power. Their military is 6 times the size of ours. And we are the ones funding it all. We just haven't realized it yet.
Now THAT is a "scary thought".
