You can't buy an African, Native American or orphan to be your servant.
People with mental problems aren't locked up in cages.
Burglary isn't a capital offense.
Women attend universities, and practice law and medicine.
Married women can own property.
You won't be fined for missing church on Sunday morning.
You won't be imprisoned for debt.
Catholics aren't second class citizens.
Jews aren't second class citizens.
Quakers aren't second class citizens.
If you beat a child to deth you'll go to jail.
Yes, you do have to go through a lot of trouble to buy a gun. But it will work a whole lot better than even the finest 18th century firearms did. (It would be difficult to shoot someone on impulse with an 18th century gun.)
Smallpox doesn't exist.
The law doesn't care if you cheat on your wife, have a baby out of wedlock, use a four letter word, or have relations with someone of the same sex.
Being a "good" American doesn't mean being a good Protestant.
I'd say these were changes for the better.
