Absolutely. Lack of effective enforcement of anti-trust and consumer protection laws are major factors in rising costs of everyday people. Corporations and oligarchs get to do whatever they want and suffer no consequences for it, because Citizens United gives power to those with the most wealth.

There was a demonstration of this asking people to divide a pie representing wealth among various low, middle, and upper classes in a way they felt was fair. The result was uneven, upper classes getting more, lower classes getting less. But when compared, the actual division of wealth as demonstrated using a pie resulted in the richest 10% getting 70% no one thought that a system that resulted in such inequality was fair.
