The brutal practice of the British continues to this day in the tea plantations of India in terms of sourcing labour. You will remember, if you had the right kind of teacher, that the Brits tried all the tricks of the trade to generate a proletariat for the tea gardens. In the end, and adopting the lessons from sugar, rubber and indigo, they settled for migrant labour from other parts of India. This allowed the Brits to impose the relations of production that suited them.
Migrant labour is still good for exploitation to this day. And sadly trafficked child labour also.
Not less than 10,000 people, mostly children are trafficked into the Northeast with a good number smuggled in from Bangladesh, Nepal and other South East Asian countries, surveys by NGOs reveal.
Most of those trafficked are then engaged as cheap labour in coal mines of Meghalaya, tea gardens in Assam and prostitution.
