I also thought of tax, and I think it is probably a good example. What is especially confusing about tax is that, for some reason, whenever anyone has an idea they add on a new bit, rather than removing an old one.
ISAs are an obvious example of this. They basically introduce a subsystem that bypasses the normal taxation system in a limited way. But a similar effect could have been introduced much more simply by just raising the tax threshold in the main system.
