liberation of the people of tibet.
This according to a study done by the chinese (of course) but it sounds similar to the above.
See:
http://www.china.org.cn/e-white/---And NO I am not attacking (or defending) Castro, just pointing out how some things can look good to anyone depending on the frame of reference AND that 'facts' (if you will) can show any country as improving over time (In this case, it seemed that the tibetan people were really screwed over until the chinese saved em):
http://www.china.org.cn/e-white/20011108/2.htm-- Backward social system and harsh economic exploitation.The society of old Tibet under feudal serfdom was even more dark and backward than in Europe in the Middle Ages. The three major estate-holders -- officials, nobles and upper-ranking monks in monasteries -- accounted for less than five percent of Tibet's total population but owned all the farmland, pastures, forests, mountains and rivers, and the majority of the livestock. The serfs and slaves, accounting for more than 95 percent of the population, owned no land or other means of production. They had no personal freedom, had to depend totally on the manors of estate-holders for livelihood or act as their family slaves from generation to generation. They were subjected to the three-fold exploitation of corvee labor, taxes and high-interest loans and their lives were no more than struggles for existence. According to incomplete statistics, there were over 200 kinds of taxes levied by the Kasha (the former local government of Tibet) alone. Slaves had to contribute more than 50 percent or even 70 to 80 percent of their labor free to the Kasha and estate-holders, and over 60 percent of the farmers and herdsmen were burdened with similar high-interest loans.
--Rigid hierarchy and savage political oppression.The "13-Article Code" and "16-Article Code" of old Tibet divided the people into three classes and nine ranks, enshrining social and political inequality between the different ranks in law. These codes explicitly stated that the life of a person of the highest rank of the upper class was literally worth his weight in gold, while that of a person of the lowest rank of the lower class was worth only the price of a straw rope. Serfs could be sold, transferred, given away, mortgaged or exchanged by their owners, who had the power over their births, deaths and marriages. Male or female serfs belonging to different owners had to pay a "redemption fee" if they wished to marry, and their children were doomed to be serfs for life. Serf-owners could punish their serfs at will. The punishments included flogging, cutting off their hands or feet, gouging out their eyes, chopping off their ears or tongues, pulling out their tendons, drowning them and throwing them down from cliffs.
