> All regulation is created for the purpose of protecting people.
That is a politically naive, idealistic perspective that does not align with reality.
Regulation often exists to serve entrenched monopolies and to raise barriers to entry. Sometimes, regulation is a purely emotional knee-jerk reaction to a particular wave of passing news or events. It's often ill-considered over the long term. Long after a society or economy has changed or evolved to the point of rendering the regulation obsolete, the regulation continues to impose costs and burdens on the subjects of that regulation.
It turns out that laws are easier to enact than to roll back. There's a bias to keep existing laws, no matter the opportunity costs.
And that's without digging into my former point, which is that much regulation is the result of cronyism at the highest levels to serve special interest groups.
> Profit comes from people do anything they screw people over for is usually obscured in some way.
Profit comes from economic value creation or perceived economic value creation in the marketplace (as determined by the market). It is revenue minus expenses. It comes from any economic activity that is conducted between two parties in a mutually agreed upon transaction in which both parties trade one type of value for another.
