In my opinion getting rid of our slave economy was a huge improvement. Life for orphans has improved in some ways although they are still vulnerable, and child abuse continues to be a problem. Life for widows and divorcees has probably improved. The poor are somewhat better off, and so are the mentally ill.
I agree with most of what you said. What disturbs must conservative Christians is the ever since the 60's our nation has gotten farther away from God. In the past 10 or so years our society has gotten hostile towards most religions but more so towards Christianity. At the same time not only has anarchy increased, it has become more acceptable.
That is a bad trend for any society.
