It appears you're referring to when I said "(assuming a highly controlled, completely reproducible experiment actually can be set up in social/economic sciences)". I'm not making this assumption, I'm questioning if a meaningful experiment can actually be formulated and performed.
If a meaningful experiment can not be performed (and I'm not saying that it can), then examining and observing how people born into rich families operate would give better, or at least no worse, information than an uncontrolled, non-reproducible experiment would. And it might actually be cheaper to study those with money already rather than give people money just to be able to study them.
