And my point is that Brazil won't get rich by doing what it is currently doing. The primary sector won't enrich the general population or make the country more developed. Only some people favoured by the current government. That's what's currently happening, not some cuckoo theory.
Brazil is rich though, and largely because of those things. The fact that such richness is so unjustly distributed across the population is an orthogonal problem.
The number of people working in the agricultural sector has only shrunk and will keep shrinking due to mechanisation/automation. The general population won't see the benefits of the primary sector growing, unless we have a Soviet-style wealth redistribution.
