I'd imagine that they don't do much, I wouldn't say they do nothing though. The alternative from West's point of view is that politicians just tell everyone "we can't stop this until we have a vaccine so some of you are going to die, but can the rest of you just go back to work anyway or capitalism is fucked for the next decade..." By telling people to wear a mask it looks like they aren't just standing around doing nothing, plebs have some hope to cling to, and everyone starts trying to behave in a co-operative fashion by washing their hands. This would only work in a truly White society, because niggers don't wash, they live 10 to a house, and White people have given up on co-operating for the future of White people because their culture and values have been destroyed by having to share their country with niggers
