1935 was wavering. The economy was at a seemingly brink of risk and Roosevelt was not going to let it plunder. Many said that the "New Deal" wasn't working well enough and thought that what they saw was the government taking over. May 1935 came around and it hit its all time low. The National Industrial Recovery Act was a key piece of New Deal legislation. However, in 1935, the supreme court struck it down. Roosevelt wasn't having any of this and so he made the Second New Deal which proposed many new parts of legislation, including Social Security.

Most blacks do not want to go to Africa during the colonization movement because they had been born in the United States and had little in common with Africans.
As you can see Africa and United States were different if I'm not mistaken the U.S used Africans as slaves back in the day so that could probably explain a lot.
Hope this helped :)
Have a great day
