Oh for sure, capitalism is built on exploitation, and it makes everyone rely on the system of exploitation that it creates. My main point is that you as an individual are not really responsible for that exploitation. The reason you are reliant on cheap imported labour in the first place is because you yourself are likely a worker being exploited by a person capitalizing on your labor.

only the exploitation went away, it's not at all clear to me that I would have a way to keep myself alive.

Just because exploitation theoretically disappears doesn't mean there wouldn't be another system of labour and resources organization to replace it. Every form of labour is equally important so long as it fulfills a need for society. There can only be so many farmers or minors.
