"Well I'm 100% certain that none of those savings was ever passed onto the customer."
What does that mean and what has that to do with anything?
Maybe the savings were used to buy a few new pumps.
Maybe the savings were used to hire guards and build a fence for security.
Maybe the savings were hoovered up through higher wages paid to attract quality employees.
Maybe the savings were hoovered up through union-imposed higher wages so that union bosses can stay in their warm bureaus for another term.
Maybe the savings were hoovered up through government-caused inflation, taxation, VAT and social security schemes.
Maybe the savings were hoovered up through government imposed arbitrary "regulation" made by bureaucrats who barely made their sociology degree at uni.
Maybe the savings were used to build the CEOs McMansion and pool, i.e. "consumption".
Maybe the savings were used to get a new contract through dining, wining and brownveloping of political decision makers, i.e. corruption.
Maybe. Who knows.
Clearly you want "more regulation" and "lower prices" and probably also "a pay rise" as well as "quality products" and possibly "jobs".
You can't have it.
