Can’t speak for Turkey or Bulgaria but what I’ve seen of Brazil tells me that there’s not much of a middle class there...just poor and *really* poor.
20 million in Sao Paolo i'd say about 10% 'upper' class, 60% 'middle', 30% poor. But the middle is being squeezed with high taxes, huge bureaucracy, and poor infrastructure. The elites and their govt cronies hire thugs to get the poor to vote to keep them in power. The govt shuttle public monies to the elites. Not sustainable and the Brazilians are so ticked-off to have been pushed past their limit.
When will we?
