Friendly Feudalism: The Tibet Myth by Michael Parenti "common practice for peasant children to be sexually mistreated in the monasteries. He himself was a victim of repeated childhood rape not long after he was taken into the monastery at age nine."

Each paragraph depicts jaw dropping abuses by the so-called Tibetan Buddhist 'monastic' serflords.

Young Tibetan boys were regularly taken from their families and brought into the monasteries to be trained as monks. Once there, they became bonded for life. Tashì-Tsering, a monk, reports that it was common practice for peasant children to be sexually mistreated in the monasteries. He himself was a victim of repeated childhood rape not long after he was taken into the monastery at age nine. [12] The monastic estates also conscripted peasant children for lifelong servitude as domestics, dance performers, and soldiers.

A Tibetan lord would often take his pick of females in the serf population, if we are to believe one 22-year old woman, herself a runaway serf: "All pretty serf girls were usually taken by the owner as house servants and used as he wished." They "were just slaves without rights." 

Such was the case with the Tibetan theocracy. Until 1959, when the Dalai Lama last presided over Tibet, most of the arable land was still organized into religious or secular manorial estates worked by serfs.

Along with the upper clergy, secular leaders did well. A notable example was the commander-in-chief of the Tibetan army, who owned 4,000 square kilometers of land and 3,500 serfs. He also was a member of the Dalai Lama's lay Cabinet. 

Old Tibet has been misrepresented by some of its Western admirers as "a nation that required no police force because its people voluntarily observed the laws of karma." [10] In fact, it had a professional army, albeit a small one, that served as a gendarmerie for the landlords to keep order and catch runaway serfs. [11]

In Old Tibet there were small numbers of farmers who subsisted as a kind of free peasantry, and perhaps an additional 10,000 people who composed the "middle-class" families of merchants, shopkeepers, and small traders. Thousands of others were beggars. A small minority were slaves, usually domestic servants, who owned nothing. Their offspring were born into slavery. [13]

In 1953, the greater part of the rural population---some 700,000 of an estimated total population of 1,250,000 [56%]---were serfs. 

Serfs and other peasants generally went without schooling or medical care. They spent most of their time laboring for the monasteries and individual high-ranking lamas, or for a secular aristocracy that numbered not more than 200 families.

The first time [the landlord's men] caught me running away, I was very small, and they only cuffed me and cursed me. The second time they beat me up. The third time I was already fifteen and they gave me fifty heavy lashes, with two men sitting on me, one on my head and one on my feet. Blood came then from my nose and mouth. The overseer said: "This is only blood from the nose; maybe you take heavier sticks and bring some blood from the brain." They beat then with heavier sticks and poured alcohol and water with caustic soda on the wounds to make more pain. I passed out for two hours.
