Things seem to be changing recently when it comes to businesses. Many decades ago, if one company rose to the top and took over in any one arena, it was considered to be okay. But back then, companies take over to the point that some point do now. When a utilities company takes over and there is no deregulation, that can be a problem. Texas is one state that has made sure to not let that happen, and https://www.choosetexaspower.org/ is a very important site to learn about that from.
When one company grows larger and dominates most of the space in a particular arena, that is very good for that company. However, when it comes to customers, it leaves them with less choice when it comes to the prices and fees they pay or even the services they receive. If one company that dominates the market decides they want to raise rates very high, they can do so, and they know that customers have no choice but to try to keep their service with that one company to get electricity. If the customer is unable to keep up with their bills because the one company they can purchase from is the only one around, then they do not have any other choices to get important service from during hot summers or freezing cold winters.
Competition between companies is good because it helps to keep pricing more competitive. Consumers then have the choice to look around at their options with each company to figure out which one they can afford or gives better service. Good and bad reviews suddenly become much more important to a company when they know they can lose customers to another company if they are not performing well. It is always a good thing for citizens to have choice when it comes to services they buy.
