Get your money up, king, as long as you’re not exploiting others. You’re right.
In capitalism there is no getting around exploiting others. Even if you have barely enough to eat this might just mean the cheap food you bought was made with more exploitation than normal (and part of it is exploiting their own consumers by ripping them off for subpar stuff).
I don’t mean that people should just “do whatever because capitalism” though, but be aware that you will be exploiting people (and the more money you have the more so) so do try to help people the more you can. And preferably by helping people in a more permanent way like moving towards a socialist society, but how exactly this help will be will vary from your conditions, your place, the time and so on.
And landlording is bad but under capitalism some may have to chose between either being a landlord/buying shares/leaving your money with the bankers/“investing” in the goverment or food insecurity/bad education/not having time for oneself… which just underscores the need to get rid of this system that puts people against people to survive just so a few can feel good about exploiting others.
You’re entirely right, but my point was that passively taking half a salary from someone for the privilege of having a roof over their head, and buying a microscopic amount of stock of a company that holds small amounts of stock in a bunch of companies are quite literally on the opposite sides of the spectrum of exploitation.
