I agree that the economics profession needs to improve a lot. Economics is a social science that deals with highly "organic" complex systems, and not a science that deals with easily measurable and quantifiable stuff like physics. I think the main issue with the modern economics profession is that it practices economics in a way that doesn't properly account for how "soft" and complex economics is. That means we need more diversity of ideas and approaches, the inverse of the uniformizing "tyranny of the top 5" we have today. But to improve the way economics is being done, we need lots of young people going to grad school to become good researchers and professors who will improve the profession. New approaches come from the new people coming in and building new "schools of thought," not from encouraging people to drop out of the field entirely.
