I could care less what Bush's family did before he was born.
Why would you have that position? I think a rational human would realize that the Bush family legacy, in Government, business, investing, and Yale were all crucial to GHW Bush and GW Bush, so why wouldn't you be interested to see how this family empire was built? Also, you WERE interested a minute ago when you asked for a link, now that one exists "you don't care".
Here's a story on how family connections likely got GWB into Yale (he was turned down by the University of Texas.. daddy didn't go there)
