Answer:
Progress decay
Explanation:
In 1830, President Andrew Jackson addressed to the Congress in an attempt to relocate the eastern Native American tribes to land west of the Mississippi River. On his message, Andrew Jackson talked about separating Native Americans and free them from the power of the States. The term that has the most negative connotation in his message was "progress decay" assuming that the decay of the Native American community is imminent but separating them will help them by "enable them to pursue happiness in their own way and under their own ru*de institutions; will ret*ard the progress of decay, which is lessening their numbers".
Have a great day :D sorry if I'm wrong!
