A proletarian revolution is a social revolution in which the working class attempts to overthrow the bourgeoisie. Proletarian revolutions are generally advocated by socialists, communists, and most anarchists. In Marxism, the need for a proletarian revolution is a cornerstone and the first step towards dismantling the exploitations brought about by capitalism. In the Marxist view, proletarian revolutions will inevitably happen in all capitalist countries"
That is from Wikipedia. Marxism was a response to the wealth gap - income inequality - which according to Marx is a result of capitalism. Marx's views are out of fashion today and considered simplistic. The hard edges of capitalism can be smoothed by welfare states and national health services such as Britain's, and such as Obama is trying to build in the US.
But developing countries such as Thailand have only vestigial welfare states and their GINI coefficients are well into the danger zone. Yingluck's rice subsidy was intended to alleviate poverty and was a misguided attempt at a welfare payment. It is unaffordable and may force Thailand into default, but it was nevertheless an attempt to narrow the wealth gap.
Thailand's GINI problems are shared by all East and South East Asian states with the possible exception of Japan, so the Thai situation could be replicated in any one of them.
Britain's welfare state was introduced after WW2 and resulted from a realization that a population that had sacrificed so much, including lives, in defense of their country deserved to share in some measure of it's wealth.
Churchill, a hero to the British but a conservative - a representative of the ruling classes - was replaced by a labour prime minister at the first post-war election. So Britain had united in adversity and come together around the idea of fairness. Scandinavian welfare states are more generous than Britain's, but that's another story.
Seen from this point of view Thailand has arrived at the point Britain arrived at in 1945, unless Thailand descends into civil war, in which case it will have arrived at 1645, the English Civil War, which has parallels with Thailand in that it was a war between parliamentarians (democrats) and royalty. That resulted in 200,000 dead, about 5% of the British population at the time.
So, 1645 or 1945, which is it?
