To me, it looks, like this is contingent on the kind of product they need to support. For instance, in storage business, L2 support are often paid more than developers (and are very hard to find!) They usually come from the development side of things, attracted sometimes by being hired in a different capacity (eg. being a consultant running their own consultancy business rather than being a direct hire), some like to go on business trips (this kind of work often involves being on the customer's site, physically plugging and unplugging equipment etc.) In medical s/w development, L2 can be nurses or doctors, they might be attracted to this position due to relatively low load (compared to clinical medicine), flexible schedule etc. I don't think there is / possible a single answer to how to find these kinds of specialists.
