During the current recession I've heard ads from various Financial Services firms in my city making it clear that their staff will do all of the paperwork in switching your super (401k) or other investments to them, at no cost.

Most Health Insurance countries here in Australia offer the same service, and then meta-provider iSelect also make it simple to compare and recommend where you switch to.

Regarding business model, it's basically a question of loyalty. If we pay you or one of our staff to help you switch, we want the pay-off to be revenue from you for a long period of time. That's fine if combined with decent client service or a loyalty program, but if you're just as crappy, and your industry starts making switching easier, it will cost you in the long run. Not the easiest way to get clients and make money.
