LOL. Water heater lasting decades . . . so you have not owned property for much more than 6-9 years. Water heaters come with 6yr warranty or 9yr warranty. They have zinc sacrificial rods in them that will positively melt away in that time span! After that is done, it's only a short time before the iron/steel containing vessel rots and leaks water all over the basement.
Those sacrificial rods can be replaced. That's assuming that sediment doesn't kill it first.
People seem to forget that the economy in the US can suck and corporations can still produce huge profits, with the profits being almost completely from overseas operations where the economy is better.
