How much higher do ppl look at when comparing an Ivy League school to a UC Berkeley?

I got into Berkeley and Cornell. I am majoring in Environmental science in UCB and biology in Cornell. I got in as an international student to Cornell(Have to pay full $40000) but as an in-state resident for UCB ($9000 tuition). Ppl are still recommending me to go to Cornell and brace the money problem because they say Ivy Leaguers are revered in our society. is it true? Does the tag "Ivy Leaguer" make that profound difference when I get a job?
