Over regulation usually helps the Walmarts and Amazons, the top of the top. Those effected the most is their smaller direct competition.
I dont excactly consider Walmart and Amazon exactly as "hoarders" either. They expand and create many jobs. Yes, they are the jobs of our great land of Slavelandia, but what people judge by is what they see which is the classic brick and mortar store's..the mom and pops shop.
The truth is Walmart and Amazon have created an incredible amount of independent middle class people with their 3rd party market places. Where businesses are lost people focus on that, but in reality many more independent middle class businesses have been created and on a global scale. My big beef is that I dont feel independent, but I work for the government. Im a government contractor. The government allows me to breath and make a living so long as I dedicate a 3rd of my life handing over my slave sweat to them prior to paying additional property and sales taxes along with school tax that I dont have any children that go to it. Half my work life is dedicated to being Sam's slave. I can do so much better if my money at least wasnt taken against my will, and if I fight back my life will be destroyed....but life is still good, just can be so much better.
