Exploitation of working class labor

Can you explain this? Landlords built their properties?

Annnnnnnnnnnnnnnnnnd . . . this is why the Left should never have been allowed to take over the public educational system of the United States. Countless dead victims of socialism and Marxism around the world just rolled over in their MASS graves.

dead victims of *Leninism and state capitalism. Is capitalism okay just because we don't have to see the cheap labor we exploit from overseas, laborers collapsing on the job, working for a pittance? Or the vast amount of resources we've plundered from underdeveloped third world countries? Is it okay because we pretend not to notice those starving in the streets, lacking clean water, clean air, shelter and quality affordable healthcare? The hundreds of thousands capitalist imperialism murders in the Middle East? Capitalism kills millions annually, that's a fact.

How would you back that up in 50 words?
You talking shit I think.
