They would be depressed to find that the amount of liberty in America has actually gone in full REVERSE. They created this nation through the Constitution to be the most liberty-rich a nation can be before it starts working in reverse. Below is a timeline (...thing...) that shows what I believe to be the average liberty levels in America.

Conclusion:
I think the founding fathers would be disheartened to find out that the United States of America has reverted to the same liberty levels as the religious extremist Massachusetts Bay Colony, or even England in 1585. For those non-Americans who wonder why we worship our founding fathers so, it is because they are probibly the greatest collective of men to ever walk the Earth. Wikipedia Benjamin Franklin, or Thomas Jefferson, or George Washington, and report back here with something bad (and non-petty) to say (other than TJ had slaves). I bet you can't do it!
*******For those who do not know the significance of some of the dates above, I have added an asterisk after every topic that I will expand on below.
-11th Amendment: "Clarifies judicial power over foreign nationals, and limits ability of citizens to sue states in federal courts and under federal law." - Wikipedia
-13th and 14th Amendments: Ended slavery.
-19th Amendment: Grants women the right to vote.
-Civil Rights Act of 1964: Basically mops up anything the previous anti-discrimination laws missed, such as the Jim Crow laws (basically, the JC laws state that "colored" and "whites" must have separate facilities, bathrooms, drinking fountains, train cars, etc.).
