I wouldn't say that at all.
Most companies (I'm speaking largely to what I know which is US businesses) charge what they change because they want to ensure they turn sufficient profit for numerous reasons..
1-To not treat their employees like slaves with only enough pay to barely allow them to eat and allow them to enjoy decent lives.
2-The want those employees to have sufficient healthcare. (that can be one of the highest expenses on a companies books actually even though employees pay some many companies pay far more)
3-They want/need to meet stringent safety/environmental,etc... standards and compliance so that people aren't hurt/killed and that our environment isn't trashed.
4-They want to ensure that they are making money so that they can continue to grow the company/invest in new technology to improve the processes as well as be able to make it through seasonal downturns in the economy.
5-recoup R&D and capitol investments in a suitable time frame necessary to continue with routine development cycles..
6-Pay tariffs allowing international business,etc...
and many..many more things that are all part of the reason for the profit margins that most employees/individuals fail to understand..
