I’m not going to criticize him for this. While it might seem gaudy to some, he’s spending his money in the economy. Even if he was building the addition with his bare hands, he’d still not to buy the supplies to do so, which I’m sure the stores would appreciate. But he’s not building it with his bare hands, so the contractors that he hires to do the addition will undoubtedly need to hire quite a few people to do the construction, plumbing, weldnig, etc., and all of those workers will spend the money they earn, so this is hardly a bad thing. It’s not like the construction industry is flooded with jobs right now.
