These practices are exactly the kinds of behaviors that regulators should prevent.

When a business gets huge it shouldn’t be allowed to buy up all of its competition. Regulatory authorities should block these acquisitions. For example, Sprint should never have been sold because it concentrated power even further and gives customers less choice.

It’s not simple price competition either. A company like Walmart can afford to sell products at a loss to drive other businesses out on purpose and then jack up the prices when they’re the only game in town. Dollar General has been accused of strategically placing stores to block businesses from making a profit.
