Actually, your example seems to be poor in my opinion - comparing peoples perspectives and awareness of the realities of sweatshops vs landlords. The exploitation isn't as readily visible in the landlord/renter relationship as it is in the sweatshops, and I believe most people who see sweatshops as immoral but a necessary evil, don't even consider landlording to be immoral. There are definitely those out there who are aware of such, but it is minuscule relative to how many adhere to your example. Because of this, I think it weakens your example. You're comparing my awareness of the wrongs of landlording, to the awareness of those who are only aware of very visible and obvious exploitations. It's easy for people to see sweatshops as wrong and not see the whole picture of capitalism as wrong. but if you're aware that landlording is exploitative, I think it becomes very hard to ignore the other countless other spectrum's in capitalism for what they really are.
