Pure BS. Doesn't work that way - just hype from certain schools (call it propaganda) to make gullible people think this way. Why is this such a big deal in the US? because celebrity matters, and celebrity schools are a "thing". While it likely won't hurt to have this accreditation on your CV, the notion that it makes the difference you think it does is a fallacy. This is part and parcel of the "we are the greatest country in the world" delusion.
