Put in a sand pit somewhere you are ok with them shitting. Training domesticated cats is an undertaking that in my limited experience comes down to giving them an option they’d prefer over their current behavior. Trying to dissuade a feral cat from shitting where they please humanely seems like a loosing battle.
Capitalism didn’t appear over night. It took several attempts and iterations to get it anywhere near what it is today. Most modern theories on the implementation of Marxism focus less on centralized government authority and more on democracy in the work place, and eliminating 3rd party shareholders’ control. Much of the struggle with implementation of this, is that the existing financial structures aren’t set up to handle this type of thing well.
