>>17864336 (OP)Boomers without question.
They figuratively killed the golden goose. They became extremely self centered due to PTSD from endlessly being bombarded with nuclear war propaganda as kids (it made them love for the moment "cause you could die tomorrow), and their insistence on tearing down barriers has lead to a race to bottom mentality for everything (culture, science, innovation, education, etc). Plus their general hatred of all other gens makes them unique in that they're the first generation(since Rome) to purposely fuck over their own kids/grandkids).
Next would probably be gen-x because they're similar to boomers but lack the culture impact boomers have.
