"Debt bondage, also known as debt slavery or bonded labor, is a person's pledge of labor or services as security for the repayment for a debt or other obligation. The services required to repay the debt may be undefined, and the services' duration may be undefined.[2] Debt bondage can be passed on from generation to generation."

Claiming bonded labor is a way to "improve the human capital of" workers means you see these people as inferior than yourself. It also means you do not believe they are entitled to basic human rights, as defined in the Universal Declaration of Human Rights: "Everyone has the right to work, to free choice of employment, to just and favourable conditions of work and to protection against unemployment. Everyone, without any discrimination, has the right to equal pay for equal work. Everyone who works has the right to just and favourable remuneration ensuring for himself and his family an existence worthy of human dignity, and supplemented, if necessary, by other means of social protection. Everyone has the right to form and to join trade unions for the protection of his interests."[1] [0] https://en.wikipedia.org/wiki/Debt_bondage https://en.wikipedia.org/wiki/Debt_bondage [1] http://www.un.org/en/universal-declaration-human-rights http://www.un.org/en/universal-declaration-human-rights
