State regulators regulate profits by adding an allowable profit (typically the 50-year running average of the S&P 500) to annual cost reports submitted by regulated industries. Inflating costs, thereby guarantees inflated profits.
Utility companies are permitted under obscure 95-year old federal regs to keep depreciating fully depreciated 50-year old copper (buried or arial) using current replacement cost to prevent collapse of 90% of the utility cost the year after the fixed plant is fully depreciated. The goal 95 years ago was to stabilize pricing so that if technology changed, phone and electricity customers wouldn't have to be shocked by a 90% increase. The double depreciation was what the utility companies said would work to solve the decades of beratement from rural voters for whom no utility could afford to provide services in an era when over 80% of voters lived in rural areas. The federal regs haven't been updated despite a flip of population now predominantly located in urban areas where deploying copper has always been economical. Even after a universal service fee is now imposed on urban phone and electricity customers to fund copper deployment in rural areas, the federal regs that permit double depreciation in the annual cost reports submitted to state regulators is still on the books.
Insurance companies discretely educate adjusters for roofing companies and auto body shops to add 20% for overhead, 20% for profit and ferret out any ancillary repairs that might be coverable under the insurance policies.
Big Pharma, medical equipment suppliers and medical service providers are also encouraged to increase pricing so that insurance companies can turn in higher costs for higher "regulated" profits.
The top five auto insurers each own 20% of a national auction business with wreck recovery yards in each NFL city where 100% of wrecked cars towed off roads are taken so that they can be "totaled" despite being safely drivable regardless of how minor the body repairs might be so that the insurance company can claim total loss while each of the 20% partners in the junkyard business can reap huge profits reselling the cars to be driven again or chopped for parts.
Since less than 20% of the country votes, less than .001 percent of the population can articulate what needs fixing, and 90% of legislators sell votes to the highest bidder, the costs for regulated industries rise at 2-3x the rate at which unregulated industries are able to increase costs and continue to do so for decades.
The only fix is to await self-implosion of the unfettered greed a la Rome. Meanwhile, nine countries have populations where over 75% of the population votes without rigged elections a la Erdogan, Putin, Kim Jong Un, Maduro, et. al., Countries where most people vote, and votes are counted honestly also typically enjoy longer life spans with 2-3x lower health care costs and also enjoy cheaper and more effective rail transportation verboten in the US where regulated airline, rail, refinery, auto and airport industries stoke their protection racket with campaign contributions.
