Gain Wealth...Forget all But Self
A lot of anarchist-capitalists, and other die-hard capitalists, like to believe corporatism is the result of socialism. At first, this could make sense, as corporations are ultimately licensed and regulated by the state; but due to capitalism, the means of production are privately owned. This leads to great wealth accumulation by those in ownership over the means of production, and the products and services produced by those means; and those owners are not the state, so it can't be state-socialism's fault that we have corporatism.
In a state-socialist system, the means of production would be owned by the state, along with the products and services produced by those means. This is not the case with corporatism here in America, as the state has no ownership in the means of production (in most cases). Even in an anarchist socialist society, the means of production would be owned by the laborers, the ultimate set-up for any truly autonomous society; but that is not how corporatism spawns either.
Corporatism is when private producers collude with other private and public producers to set prices and markets, while incorporating themselves into the legislative and policy making process to create monopolies, through the financial capture of the state.
When people say corporatism is caused by socialism, they are confusing the state's action under our Democratic Republic as state socialism, but America is not a socialist country, therefore socialism cannot be the cause or corporatism. In America, corporatism is the result of capitalism combined with our captured Republic, which is a result of foregoing our human interests and replacing them with artificial monetary interests.
A free market operates in any system where government is not a participant, it does not mean you have to be shackled to capitalism to achieve it. In fact, capitalism, as we are experiencing is vulnerable to outside political forces under a Republic, and capitalism has been perverted to serve nefarious needs no truly free market would ever produce, like the creation of the monopolistic corporate-state.
The solutions to ending corporatism has to start by moving away from our corporate statehood, by somehow removing money from the legislative process. As long as our Republic can be purchased, the wealthiest business structures, regardless of size or set-up, will eventually seek ways to gain advantages through the state.
This will always leave our Republic vulnerable to the those who control the most wealth, something only direct democracy could quell, but we do not have a direct democracy, forever leaving us vulnerable to the corporatist and the policies they enact through a captured state and economy.
