This is the point I'm trying to make, they have had a long period of economic growth, people will put up with a lot if they see their situation is getting better. The question is what happens when the growth flounders.
I don't see this happening in the immediate future, except maybe temporarily due to global economic issues. I'd expect it to take at least a decade until this becomes a problem and as the article shows, China is certainly planning that far ahead and is able to execute these plans.
Making and executing long term plans is definitely something China has a significant advantage in compared to the democracies in the west.
