I think it was because big corporations saw Trump as dangerous to the economy. Clinton was a safe choice. Trump, well, he would start a trade war. He said he might default on the national debt. He would deport 11 million illegals, which would hurt business and also hurt the economy. It wasn't just big business, economists, experts, newspapers, they heard what Trump was saying and they did not like it one bit. I think it is telling that Trump got the most support from the poorly educated, that he even said "I love the poorly educated." He was clearly unfit for office and dangerous. Clinton was fit to serve and a steady hand.
-Tell that to the people of Mali. And why do you hate the poorly educated?
