Start by undereducating a population. Tie school funding to property values, so that existing imbalances are accentuated in the next generation. Promote a mentality of punishment, even for minor offenses. Always push the framework that an individual is solely responsible for any actions, even when there are overwhelming societal issues.

That sets the tone and the public support for the direct actions to come next. Have increasingly severe punishments for minor crimes. If any politicians speak out against it, run ads describing them as "weak on crime". If necessary, invent entirely new crimes to target the groups that you want to target.

Now you have a captive population, and public support for punishing them. Since the framework emphasizes individual actions and individual "debts", there is no backlash in having that population work while captive.

Slavery is deeply wrong, and exists in the US today through the prison system.
