American settlers continue to spread to the west and took land from Native Americans. As expansion continued, agreements were signed and they were broken with native americans losing their homes and land and force to move west. As Native Americans were forced to more to the west, they are not able to adopt to the environment they are moving to, so they died due to lack of food or diseases.
Reduces their power--elites in Latin America control economic and political aspects of society. Reforms would provide more groups with rights, reducing the influence of the elite.
In any country, elites often control the means of production and the political system. Reforms, especially coming from lower classes or oppressed groups, would potentially reduce the power and influence the elite group has. This has been true through many revolutionary movements.
Slavery during the 17th century worked more like indentured servitude. The first blacks to come to the Americas were indentured servants. They worked off the debt of their passage and were given land following their servitude. The whole system of indentured servitude fell away after land resources became limited. Blacks were allowed to purchase their freedom, buy land, even some having their own slaves. As the colonies entered into the 18th century, the black population was increasing as slave labor became more important to the plantations. Increasing numbers coupled with slave revolts led to the creation of slave laws in many of the colonies. These laws made slavery lifelong and a status associated with birth to a slave mother. Though slavery was becoming less common in the British Empire, when the US became independent, slavery became a part of the new country's economy and social structure.
