Markets need fertilizing and weeding, ore else are destroyed
Traditionalists say any government interference distorts the "natural" and efficient allocation that markets want to achieve.
Complexity economists show that markets, like gardens, get overrun by weeks or exhaust their nutrients (education, infrastructure, etc.) if left alone, and then die--and that the only way for markets to deliver broad-based wealth is for government to tend them: enforcing rules that curb anti-social behavior, promote pro-social behavior, and thus keep markets functioning.
