Answering this correctly many years ago got me a job on Wall St. You don't have to look inside since the expected value after switch is always 1.25 higher. So if you accept this logic you will keep switching unsealed envelops forever. The answer is not to switch because there is no new information gained when looking inside the envelope. The amount you see does not help you decide.
I thought the way to get a job on Wall Street was to solve a Rubiks Cube :D

Wow, quite fascinating this is what got you a job inside Wall St.
You are right on this:
The answer is not to switch because there is no new information gained when looking inside the envelope.
but it makes me wonder how many Stackers know about the Monty Hall problem. I never posted it as I assumed everyone has heard of it at some point. There, the
new information being gained condition is harder to assess...reply
Fun fact, your puzzle today inspired me to teach my kids the Monty Hall problem. At first they were like, "What difference does it make?" But they seemed to understand when explained. Hope they remember it
