Why aren’t the improvements made by Americans constitutions enough? What complaints do citizens still have?

Please read below!

Explanation:

Really there are a lot of things that people complain about. Somethings are just unnecessary to complain about but others are. Although people have rights in America, different from other places in the world, people don't feel like they are being heard or thought of. Still some of the things that are going on right now in America are the race and religion issues that in my opinion just need to stop, but people feel like they are not being heard because nothing is being done to stop things from happening.

People are dying for example because of skin tones, some are being put down because they say something wrong. But in the constitution, everyone has equal rights, and the freedom of speech. So why does it not feel like that?  I am sure there is more like the injustice in the courtrooms and other things, but I will just talk about the things that are being discussed in time right now in history.

I hope this helped!

the answer is a) the proclamation of 1763.
