Pa(b)st Prime: "...I see America's future. It's Brazil."
Please expand on this. I do not know what you are implying, and I live in Brazil (retired there 14 years ago from USA).
As I foresee the future, the dollar will continue to drop and the Brazilian Real will continue to get stronger relative to it. Brazil will continue to increase its balance of trade surpluses, it GDP, its living standards, it international reserves, (too bad they are mostly in dollars, but Brazil will soon learn better than to do that.) Etc.
Brazil will, like everyone, be hurt if the fall of the dollar turns into a run to get out. I.e. hurt in the global depression that follows, but less so than most.
This is because the factories in China and India will still be working at full capacity to satisfy their growing domestic demand. For example, only 3 of every 1000 Indians own a car and Tata Motors will soon be selling one for $2500 (US dollar equivalent) that many can afford. China's Chery Motors model QQ is already being sold for $5000. The domestic markets, not the "cheap labor" is why every auto maker in the world is building new plants in Asia while closing them in the US. Already, only China makes the world's computers.
Embraer (Brazil's Airplane company, third largest in the world) and China are now making in China 100 seat or less planes in a new factory and China is building new factory for larger ones so it will not need to buy any from Boeing or Airbus. Etc. for any high value product you wish to name in a decade or less.
China's rapidly growing and prospering middle class will have more purchasing power than all Americans in less than a decade. Etc.
India, and especially China, will still (and increasingly) need to import raw material and food stocks from Brazil, and others, so part of their high value product production will be required for exports to pay for their supplies of raw materials and food.
I.e. China and India will not have any surplus production* to sell to the US, which is consistent with the fact that after the dollar's fall, the US will not be able to continue borrowing to pay for imports etc.
Thus, I expect that in a decade, the US will have a trade surplus with China as although the US does not have much in the way of raw materials to sell to China, the US does have fertile land in the mid-west.
US may be able to become an "agricultural colony" of China, if Canada and Argentina do not under cut the price of wheat too much. (Brazil can not produce wheat as cheaply as the US can, but in other agricultural products, the abundant fertile land, good rains, cheap labor, 12 months frost-free season, make food and alcohol production in Brazil much cheaper than in US.)
SUMMARY: If speaking on a decade or two time scale, and meaning the US will prosper like Brazil, you are too optimistic.
If speaking on a decade or two time scale, and meaning the US will be a "basket case" as Brazil once was, then, perhaps you are correct.

*Normally their productive capacity would be further expanded to sell all they could to everyone as the fixed cost are spread over a greater volume; however, in a world with limited energy and mineral supplies, the incremental cost of the raw material and energy required to expand production is probably rising faster than this normal cost benefit of expanded production.
