They receive tons of money in grants and don't pay taxes or rent.
And if they didn't they'd go belly-up. Pay the $25 or whatever it is. You're seeing millions, if not billions (if you actually want to put a price on the priceless) of dollars worth of art, culture, and history. And government investment in the arts is always the first thing to go when a certain segment of the political spectrum gets into power.
On average, close to 76% of a museum's funding in the US comes from non-government sources (Private donations and investments, ticket sales, interest on trusts, etc.)
America is rare worldwide in that our museums and other places of culture receive the least (or close to it) amount of government funding among wealthier nations. Big banks, for all of their faults, are among the biggest benefactors for the arts in the country. Prized pieces don't really decrease in value. They buy, lend to museums, and sell them in a few decades to someone else.
So, long story short, they need that $25 to survive.
