I do agree with you that this is a failure of regulation. However, in the stage of capitalism we are currently in, capitalism actively FIGHTS regulation.
Whether it's lobbyism, hiring "scientists" to challenge independent studies, outright tax evasion, or simply accepting fines for disaster after disaster (oil spills, bad plane design, data sales) because they can afford it. Hell, politicians now are deregulating our countries by privatising or de-funding branch after branch (see the NHS in the UK).
Capitalism at its current stage is just a giant fire-sale, and our governments are as deeply involved as the corporations, not out of maliciousness, but due to how the system naturally drags everybody and everything in, with its need for constant growth. You know what else constantly grows? Tumors.
Sure we do need powerful regulation and regulation enforcement, but we also need to think whether a system that produces statements like this: https://jacobin.com/2022/05/pete-buttigieg-free-market-hungr...
"Pete Buttigieg: Hungry Babies, Regrettably, Are Just the Price of the Free Market"
Is worth preserving.
I'd say not, and I will work my best to dismantle it and throw it in the past, where it belongs, along with slavery, feudalism, fascism and other obsolete and harmful human societal arrangements.
