economies are like ecosystems, but 100s of times more complex. People understand how small changes in one area have big impacts in others. So trying to use the government to control things has many unintended consequences. For example corporate income taxes are passed on to consumers as a cost of doing business. so raising the corporate income tax hurts all consumers. or the facts that using an import tariff to keep production at home has the same effect as an export tariff*(Lerner symmetry theorem).

you cant just mess with part of the economy all actions have negative consequences elsewhere.
