Absolutely. But we must import, it's a necessity. Think technology, pay for patents, heavy machinery, natural resources we don't have. We're becoming self-sufficient in oil (97%), but when that wasn't the case, we had to import it. With dollars? We can only have dollars by exporting things. Also, Brazil produces much more meat than it could possibly consume. There are markets eager to buy it. Most importantly, having those dollars provide a safeguards to external crisis - that is, we suffer less if (when) the economy of countries such as Mexico, Russia, Argentina collapse.
2) Why are not poor countries exporting some other consumer good ? Hi-Fi, Stereo, computers, cars, shirts, pants, etc. ? I mean, they cost 1/4 in Brazil than what they cost in Europe ( at least, I suppose )..
Nope, electronics in the US are much cheaper than in Brazil. It happens that our income per capita is much lower than that in the US, so less people buy less of everything.
Brazil exports cars to the whole of South America and small airplanes to the world. Our prices wouldn't be competitive, because of scale, if we produced for our internal markets only. That's another reason as to why countries export - to make products cheaper to themselves!
3) I still can not see why Europe started from zero ( middle ages ) and got developed, OK, maybe exploiting other countries, but Europe ( and US and other nations ) got eventually developed. Now, I think you agree that Europe and the US are not exploiting developing countries any more, so why are developing countries not getting developed quickly ??
They have natural resources, meat, iron, big rivers for electricity, ..
Call me optimistic, but I believe that the natural course is that, even though some countries started their industrializations later, they will develop. Europe got a head start with imperialism, and ensuing exploitation, plus looser standards for environment and worker's conditions. You can't, nowadays, do that without risking international outcry. So enterprises in general are much more expensive. The US is a superpower, in Europe there's the EU, those are very strong forces that are keen at keeping the status quo.
For example, when last year (was that it??) the US ended its steel tariffs, some thousandos of jobs were created in Brazil (I forgot the number and I'm tired to look it up). Entire cities have benefited from that.
