I have mixed feelings about this article. The central point about regulation and consolidation is true:

By ensuring the operation of a business requires a level of compliance costs and complicated bureaucracy that only massive corporations can afford or manage, all chances of real competition to those corporations are eliminated.

But the repetitive blaming of "the right" and "conservatives" by the author is both inaccurate and bizarre. The author either doesn't fully understand how we ended up where we are, or is more eager to blame a political party than they are to call out the true root cause. For example, this statement:

In many ways the market forces the right has lauded as a blanket solution to all social ills have been the very thing working to destroy the middle-class

The free market has done nothing to destroy the middle class. As mentioned in the previously quoted section, it's government regulation and barriers to entry that have changed the economic landscape. This is the opposite of a free market.

The author pushes this misrepresentation even further, with lines like this:

Many conservatives justify this by pointing to the fact that these corporations are able to provide lower prices and therefore a better standard of living for everyone.

This isn't at all a "conservative" talking point. Again, instead of acknowledging the root cause, the author would rather push the issue off onto politics. By blaming conservatives and the free market, the author simultaneously makes this into a partisan discussion and detracts from the value of an economic system free of government influence.

At least the conclusion makes it clearer that the author was trying to convey that Republicans need to break up the cozy relationship between government and big corporations. If that's the message, there needs to be more emphasis on (and understanding of) the value of a free market. A free market is where deregulation will take you, and putting a thumb on the scale in favor of either big business or mom and pop stores necessarily means having more government involvement. Switching which side is favored by regulations and barriers means competition and market forces are still stifled in the end.
