And what would you do if you were told when you were growing up that you were actually from a very rich family? Would you want to meet them? Would you wonder why your family doesn't have money like they do? Would you resent your parents for living a poor life rather than a rich life? Would you brag about it at school? Would you develop a sense of entitlement from knowing what your lineage is? And what if you reached out to the family only to be rejected by them? Or what if they accepted you and gave you access to the lavish, elitist lifestyle your parents didn't want for you to grow up in?
These are some of the things that his Mom and Dad probably wanted to shield him from because they didn't want him to be part of that world and to have a silver spoon in his mouth. In this regard, they were doing what they felt was best for him and that's something parents typically do. As a result, the MC seems to have a fairly good moral fibre in most respects, and that is reflected in his speech at the end of episode 5 as it shows an attitude towards life and work that has been forged by not being someone who has a sense of privilege and entitlement and knows the value of hard work.
Him being from the Burgmeister clan would be a particularly powerful shift in power dynamics as this person who seeemed like nobody is now somebody. It could cause all sorts of friction and drama that would be perfect for this story, like seeing how Rusty reacts to finding out they're cousins, or how both Tommy and Quinn would treat the MC particularly if he has access to money, and if Jill would see him any differently as she seems to like the fact that he isn't from an elite family and is just an ordinary guy. It's a perfect "drama bomb" to drop on the story as there are so many angles to it that you just wouldn't get if he was the grandson of some other random wealthy family.
