The camp I'm staying at for the May Day brigade has ~120 Americans, many British and even some Australians. If you're from those regions and wish to experience Cuba like I am (with direct contact to farmers and doing field work with them, participating in the May Day demonstration with over 500.000 people in Havana, and actively learning about Cuban politics and their institutions) there must be many, “cheap” options for you!
I've heard from one American that they had to pay ~$800 to come here through Cuba solidarity networks, which is the norm. I think that's really cool!
We may question what our job is, what it is that we can do, not from a white saviorist perspective, but within our own countries to better the conditions for the Cuban people? Well, we're at the belly of the beast. By preventing European nations and the USA from exploiting the global south, we'd create the conditions for the Cuban project (among many others) to flourish!
