What's being proposed is a grand conspiracy theory. That across most companies across all the states in the country they've all decided to be evil and greedy together, they're all supposedly run by greed heartless bureaucrats, and in the last few years in particular they've all decided together, in a grand conspiracy, to unanimously raise prices at the same time and extract as much profit as possible.
Yes, it's all a grand conspiracy involving thousands of people and companies that are all evil and greedy. It's definitely not just that economic and political decisions that were made have had an effect. It's corporate greed that's the problem.
The conspiracy doesn't even make sense. If all these companies were so greedy, wouldn't the best way for a company to make money in this world of greedy corporations be to just keep lower prices, which would result in stealing all of the business from the companies that raised prices, and thereby making more money?
