I think it's an interesting and reasonable question but I'm not sure the basis of the question is correct. First, the 2000+ years of capitalism assertion is fairly flawed, consider feudalism, but for the sake of argument lets say capitalism goes hand in hand with industrial revolution era. Then when you say 'massively efficient capitalist system' it seems like you're referring to a "net efficiency" in terms of production of wealth, and that allows a community of grifters to benefit from that as a kind of downstream recipient. You are touching upon a valid point, this lifestyle is a function of current society and it appears to be parasitic rather than self-sustaining. However, I would argue that this demonstrates that current capitalism is actually pretty inefficient to allow this.
