1) Current accounts in the region are overwhelmingly negative.
2) Trade balances in the region are mostly negative. If they're not negative, they're no where near the levels of 2008, and trending toward deficits.

So, the dollars "flooding" LATAM are mostly in the form of debt. If the vulture funds hadn't got in the way, Argentina would have joined the party already by now.
A country cannot sustain itself taking on loads of debt year-after-year without growth. Ask Portugal, Spain, and some other European countries how that worked for them. They're the most recent examples. Of course, the country you're in is also a good one.
