What I see is that they have pretty poor build quality when you look closely, and are thrown together as cheaply as possible, and are not designed all that well. Where I am, "marble" would be engineered stone (which I don't have a problem with it's functional and looks okay), but many new kitchens (and bathrooms) aren't well designed for the space they take up and come with flimsy gimmicky fittings and appliances.

Where modern houses go overboard (in my opinion) is optimizing floor area per dollar and making them very large and lowering quality. Although that's also a response to buyer preferences, people like having very big houses and don't care too much about the design, the details, or efficiency.
