I'm not saying white collar professionals can't apply and go on these shows but I think you need a mix of people from different backgrounds and to me, it's more fun seeing say a supermarket worker win big over a doctor.

In terms of Millionaire I’ve seen arguments for both

Someone who 5 figures would change their life won’t gamble, and then we end up with a parade of 16/32k wins. I’m sure one of the early Clarkson series was like this

Someone who has money is more likely to gamble and get closer to the million pound question, but are then less relatable to the audience
