" Indentured service " was not quite slavery. Here is how it worked......a youngster would be taken in to learn a trade, by a master in a trade such as a capenter, mason, wheelwright, or black smith, for a set period of years. In return for their labour, they were fed and housed and clothed. At the end of their service they could continue to work with their master, or set out on their own.
This system allowed children from poor families to have at least some chance to become educated in a way to make a living for themselves, in the days before formal education was universal. BTW, the indentured servant sysytem was NOT based on skin colour, but on class, and poverty.
Females were restricted to work as household servants, such as cooks and washer women, or seamstresses, and child care workers. Savings to be able to marry were scarce, and social class also restricted the indentured servants chances of moving up, thru marriage. Hard as it maybe to consider now, social stratification was ironclad, and marrying "above your station" was unusual, especially for young men.
