Unfortunately, we seem to have reached a plateau in solving the problem and progress has slowed (or stopped). At least, that is the attitude of a significant majority of Americans. The chart above is from the Bloomberg News Poll that was done between September 20th and 23rd of 1,000 nationwide adults (with a 3.1 point margin of error). Note that only 27% of Americans believe race relations are getting better, while 70% believe they are not (43% saying they are staying the same & 27% saying they are getting worse).
I tend to agree with the 43%. I don't believe race relations are getting worse (although the racists have been louder and more open since the election of President Obama). But I do believe we are not currently making much progress, and that's a sad commentary on a 21st Century society.
