I know it doesn't, but unfortunately it is often how it works. More than I want to remember I have seen things like 'but lives depend on this!' or '100s of millions can get lost if this doesn't work!' and yet when the RFPs come back and something like InfoSys is chosen because big name and cheaper than experts in the field.

Better education? But I guess strongly enforced regulation will force companies to not go for the cheapest solutions they can get away with which in turn will require people with actual knowledge in the field which will require better education, somehow.

Sometimes it's all about tradeoffs. For example, a split bobbin is actually undesirable in most transformers because it reduces coupling between the windings, reducing the efficiency of the power supply. That's why if you look inside a better-quality power supply you'll often find that they have a split bobbin for the input common-mode choke and then a single bobbin with layered windings for the main transformer.
