Marxists do not seek “domination” of others, nor do Socialist countries extract “rent.” Using a portion of the social fund to create infrastructure, social safety nets, advance productivity via new Capital, and more are not the same as a landlord extracting surplus value on the basis of owning a scarce resource like land. I think you’re confused on several areas, like what Marxists want, how Socialist states function, and what “rent” is. If you want, I have theory I can recommend for you.
