If you count the top 10 business school against Top 10 EE,
hard to say. Most of the founder of high-tech companies are
from EE. But if you are not from the TOP, as a MBA you are
nobody. What MBA taught you? Nothing is valuable except your
connection with your classmates. So if your school is not
the best school, your connections are useless.
BTW, mean here is not as valid as median if used as the
expected income. Since the distribution is heavy tail.
10% rich persons may account for 90% income of the whole
group.
