You make a very useful observation - that an Ivy League education is not ideal for everyone. Given your interests and goals, it sounds like you would have been better served at a business school and/or a university that integrates co-ops into its curriculum, like Northeastern or Drexel.
Two other relevant examples often come up on these boards, for which the most prestigious pick may not be optimal: For med school, students are often advised to select more economical and less competitive choices as a strong GPA and MCAT score is more critical than the name on the diploma. For prospective teachers, a regional public university is often a better career launchpad than a more prestigious school (not to mention often less expensive; an important consideration when entering a less lucrative profession.)
While you may have regrets, I doubt that your career would have been accelerated without a college degree. As others have said, the Yale name can be leveraged. Use it to your advantage. Best of luck as you move forward.
