Oh yeah we are devolving, there are a lot of reasons for this, one is technology has replaced the need to think, if you have a question you simply type it into google and the computer finds it for you, you don't even need to know how to spell it right google will do that for you too.
Then you have the assault by the left on our education where 2+2=4 is no longer enough, we have to make sure that little Johnny feels good about himself and can put a condom on a banana.
Next we have the left who constantly tells people that they can't make it on their own so why bother trying, just demand that the government step in and give you what you have been taught that you are owed.
Then we punish those who achieve, we tax them at higher rates, we tell them every chance we get that they didn't build it, someone else did.
So society has turned into a group of people who can't think for themselves and demand that the people who can, take care of them.
So perhaps getting rid of the pyramids isn't so bad after all, it would just be a monument to when people could do things, and that will just hurt the self esteem of people in the future, and we can't have that now, can we?
