In those countries the lack of democratic centralism is plain to see and if one is fearing bourgois sentiments then a significant authority of power still resides in the parasitic classes with all the failings that structure brings. The dictatorship of the proleteriat is a necessity to advance social development; it is hard enough battling imperialist and fascist forces let alone concede space for their “freedom of expression” with the weight of brutalising capital behind them.
Edit: clarity/grammar
If we define the worst countries as the ones that can affect the most people negatively by capitalism; this means imperialism, and also to consider if the country in question has a domestically large enough population to affect.
Which means, aside from the countries mentioned, they could be: UK and India.
