this isn’t a binary situation, but rather a spectrum
I disagree. It is binary, either the word is meaningfully applied in this context or it isn’t. You said that capitalism “enables” exploitation. Being alive enables exploitation. Capitalism may encourage exploitation, it may increase exploitation but I wouldn’t say it “enables” exploitation.
Unless you have some argument that capitalism somehow provides some specific cause to enable exploitation which is absent from all other systems, while all other systems also provide some different cause which also happens to enable exploitation, your statement that capitalism enables exploitation is incorrect. The specific cause that enables exploitation is being alive and is nothing specific to capitalism. Capitalism is not what enables exploitation. Capitalism does not enable exploitation.
Yes, capitalism enables exploitation by allowing people who own capital to decide working conditions for people who do not. This is why exploitation is seen everywhere capitalism has ever been tried. I’ve also gave you a concrete example contrasting communism in USSR and the transition to capitalism along with all the horrors that followed. You just proceeded to ignore that.
People deciding working conditions for others is not absent from all other systems.
