Indenturing Considered Harmful

 "In 1640, a black indentured servant named John Punch left his master’s service, citing harsh treatment, before he had fulfilled his contract, and two white indentured servants left with him. When they were caught and returned to their master, the white servants only had four years added to their time; Punch was sentenced to servitude for life. After 1640, relations between blacks and whites increasingly changed as white servants received better treatment."

 Did you know that accusations of racism were thought up by blacks, not whites? 

 We know from numerous well-documented present analogues. Punch (lol) made up grievances to get out of keeping his own word. "Y'all are mean to me just 'cuz I ain't white." Whether he was a flagrant liar or genuinely hallucinated is not known - because the difference is immaterial. In an attempt at a smokescreen, it would seem he induced two other worthless layabouts to back up his false charges, and as a result was held accountable for their dishonour as well as his own. 

 Blacks receive worse treatments because they behave worse. 

 Though also the master was at fault. Indentured servitude is imprudent. Anyone productive could have paid for their own ticket - but also, they already had a job in england, and didn't need a ticket. Retribution be vitriol, as per usual. Naturally indentured servants are going to lead to regret.

 

 Ironically, punch was somewhat correct. His bad behaviour was due to his nonwhite culture, hence his bad treatment was indeed the result of his nonwhiteness. His master had unconscious expectations of maturity, integrity, and responsibility that punch simply couldn't meet. Few ninjas have the capacity to assimilate, and few limeys have any willingness to make the accommodations these foreigners need for any kind of behavioural acceptability.  You can get the same quality of labour from bigot minors with single-digit ages, at the price of painfully similar accommodations. 

 Ninjas don't understand principles, or the fact someone might judge them for their character. They only understand dominance and submission, and their memories aren't long enough to remember they're not top dog from one day to the next. Normally this means you have to beat them (e.g. in a fight) every day, to remind them of their place. If beatings are illegal or even merely unprofitable, ninjas are unemployable.
