It's all performative and a distraction from the fact that the Met Gala is literally an event for rich people to show off their incredibly expensive clothes that will only be worn once. Unmasked while the servant class is masked, helping them get ready, carrying their dresses and serving them food and drink.
Tax the rich is a fully coopted slogan and is in fashion among the ruling class. Wearing a dress that reflects their fashion is not storming the Bastille or making them uncomfortable at all. They loved it and it worked great, considering how many peasants are defending their largesse during a pandemic. Get back to me when Senators worth $50M and the attendees who paid $35,000 for a ticket are actually getting taxed.
