"My friends, circumstances render it impossible that you can flourish in A civilized community. You have but one remedy within your reach, and that is to remove west. And the sooner you do this, the sooner you will commence your career of improvement and prosperity." Who would have most likely stated this comment?

The correct answer to this open question is the following.

The individual would have most likely stated this comment was the United States President Andrew Jackson.

In the times of President Andrew Jackson, the US federal government did not have the best relationship with the Native American Indian tribes. Indeed, he signed the Indian Removal Act in 1830, specifically, on May 28. The idea with this legislation was that the President had the faculty to grant lands west of the Mississippi that were not settled in exchange for the lands that belonged to the Indian tribes.  

Some tribes like the Cherokee opposed heavy resistance to be removed and presented fierce opposition. But finally, they were removed in 1838, in what was known as the Trail of Tears.
