My enemy's enemy.

When running into battle, having a firm grip on your spear isn't enough; the shiny end has to be pointing at your enemy. Its the difference between doing him an injury and doing him a favour.
All of your sharpening and preparation; all of your strength and cardio training won't just be wasted, they'll be applied to the benefit of your enemy.

We see this with antibiotic resistant strains of pathogens in hospitals. Superbugs, which have adapted resistance to the weapons we've deployed against them.
Germs are usually pitched in constant and vicious competition with other germ species for scarce resources like nutrients and space; but their competitors vulnerability to bleaches, disinfectants and antibioitics means supergerms have free reign to consume and breed unchecked in hospitals, often killing the people they infect.
They don't spread outside of hospitals, except inside patients, because they're not actually 'Super'. Except in circumstances where they're given a monopoly on resources, they're actually pretty pathetic.

A few years after closing a hospital, you'll struggle to find any superbugs at all; they will have been competed out of existence.
They need the chemicals that were designed to kill them in order to survive. They've become completely dependent on their niche environment.

We also see this with business regulation. Megacorporations which have adapted their business practices to the elaborate, multi-tiered regulatory environment purported to curtail their excesses.
While less regulated industries are usually competitive battlegrounds, where only the most efficient and responsive businesses win the customers, heavily regulated sectors like banking and insurance tend to be dominated by a handful of oligarchic corporations.
They're not efficient or innovative or serve their customers well; they can only grow into supercorporations because they're not being eaten alive by small, agile competitors. If the maze of expensive, onerous regulations all vanished tomorrow, we'd find within a few years all the customers would have moved to hungry, eager startups offering novel new products at lower prices.
The corporations need the regulations that were designed to restrict them in order to survive and thrive.
They're totally dependent on the regulatory environment they've learned and budgeted to navigate.

With this in mind, the idea that we should allow the largest, established corporations to advise on regulation of their entire sector seems foolhardy; and it is.
When you hear that government regulators are consulting with industry groups, understand that those groups are full of representatives of the big corporations; and they often write new regulations themselves, saving legislators the trouble of penning their own. They're particularly accomplished in writing regulations who's effect is to completely destroy a new business model before that model has gained any real traction in the market, bankrupting the entrepreneur and sending a warning to others.

The legislators get to pose as champions of the common people, "enacting sweeping new restrictions on business" while actually doing their friends a big favour.
Those friends aren't interested in looking after the customer, they're interested in keeping potential competitors from taking away their monopoly, and they'll use the full force of the state to prevent anyone from making you a better offer.

Have a fantastic day
