I don't know if this has carried over across the pond, but PE firms have been
buying up vet clinics and jacking up the prices.
Yep, Vets exactly same as dentists, opticians, funerals, nursing homes, solicitors, children's nurseries and so on. Most are now part of a big VC backed corporate chain that maximise price, minimise wages and take the difference out as profit/dividends to shareholder. Same or lower quality of service but higher price.
All part of the creeping corporatisation process that is pushing the cost of living beyond what normal people can afford.
The other thing with vets is that they are exploiting the fact pets have gone from being somewhat impersonal possessions (like cars or farm animals) to being 'fur babies' and part of the family.
If your car was worth £500 you wouldn't think of spending £1,000 to fix it, and years gone by when people were less sentimental if your dog cost you £10 you wouldn't spend £100 to fix it, you'd have it put to sleep, and buy another one.
Now with Supervet & Co. you can access the same level of medical tech as humans and are made to feel that you should spend whatever it takes to extend it's life for a year or two.
I work on a farm and it is noticeable that the large farm animal vet prices are nothing like the small animal (pets) cost. Visit from a vet, inspection of cow/bull and letter to say it is fit for slaughter or whatever, plus possibly an injection is around £100 mark.
