Don't you find Americans going to Cuba and spending all there money there anoyyin?

I'm Cuban and I find it anoyyin wen I see all these gringos byping the united states laws to get into Cuba which is a communist country. Also all the money spent there goes striaght to castros dictatorship. Ithe usual sight is a buch of pure American spring breakers who either go through Canada or Mexico, and the occasional Cuban bringing there husband or wife. I was wondering your opponion on this because I find it frustrating because all these tourist spending money there prolong communisum even this embargo isn't enough cause china which is supposly or best frend has connection with them
