Should the electrical wiring be visible on the inside of newly installed kitchen cabinets?

A friend of mine had his kitchen remodeled and the wiring for the cabinets is visible in the back of the cabinets. It is also stapled to the side and the back of the cabinet and runs to the bottom corner to the recessed lights. I told him electrical wiring should not be stapled and not visible. I have never opened a cabinet with exposed wiring. Not only that but the molding is not secured to the external cabinet. The doors on the front also have a 1/4" or so gap when closed. I said the doors need to be flush, almost touching. Not a gap like Dave Lettermans teeth.
