To be less obtuse:

• internal colonization struggles with the indigenous

• internally stratified between metropoles & areas that are so undeveloped they are practically feudal

• facilitates extraction from surrounding regions to metropoles in imperialist countries

• army & major parts of the state apparatus are locked into this, hence lula getting in hot water for weapons shipments to israel that were ordered under bolsonaro. the risk of military coup is used by socdems to justify being softhanded

• racial caste system (okay here is where india (india is worse in almost every way) is most distinctly worse but I'd rather not talk about gross stuff actually even though I may have an off-kilter sense of what is gross)
