You're wrong and I'm not even American. Apart from the occasional homeless all around town issues, the breath and depth of galleries on offer, all mostly free, is hard to top to be frank. Been to many capital cities around the world, so I speak from experience. I'm not fan of the man, but the White House needed a space like this instead of the white temporary tent they would erect.
There are massive convention halls and hotels literally across the street from the WH…. So no, this shrine to MAGA did not need to be built.
