Don't see how, because we have never had a "free market system".
The "free market" libertarians jerk off to is just as much of an unattainable unicorn as the "classless society" communists jerk off to.
The reality is, power will continue to concentrate where it is already concentrated. Government, corporation, it makes no difference. Any organization with too much power will use it to gain more.
It doesn't matter whether you vote Republican or Democrat. Both are owned by the same powers that be, the whole thing is a dog and pony show.
