Harvard doesn't offer academic scholarships. If you can't afford Harvard tuition it's free - e.g. if your parents make less than 65,000 (20% of Harvard students) you don't pay anything. So yes, it's actually massively worth it if you can get in, because you graduate with no debt and have a name-brand diploma and access to an extremely well-connected group of people. It's the kids who go to second- and third-tier institutions and take on massive debt who should reconsider college, not the ones going to Harvard.
