Corporations are accountable only to their shareholders, and even those have power only when they have very large holdings. Corporations are bound to try and maximise profits for their shareholders. Others have a caring public image which may not be justified. They cannot be expected to spend more than they need to protect the environment and clean up after them. Strong, but accountable, government is essential in the interests of us all.
Communism is a restrictive form of government, allowing little freedom of dissent.
It finally gave way to popular pressure in the USSR and its satellites. Corporatism is more insidious, as it is never called by that name, and there is the pretence of democracy, while behind the scenes politicians are being manipulated by the puppeteers. We need government which will resist the pressures of Big Business and other pressure groups, and maintain a fair market place, for employers, consumers and employees alike. In other words, government may be bad, but lack of government is worse. Men have a right that these wants should be provided for by this wisdom.
