Don't forget the Internet Boom that fueled the '90s. That was a major factor also.
My MIL (who is a great lady otherwise), loves BJ. Went to hear him speak last week. According to her, he said that he was "fortunate to have the .com/interent boom during his presidency".
That was also the decade of "Global Warming".
Warm weather is very good for crops, economies and other living things.
