In my space (Veterinary) there has been a ton of this. To people who are used to the way things were, it's been very disruptive. Lots of boomers are retiring and a young vet would only be able to pay a 5x multiple, perhaps, but PE is swooping in at 12-15x. They usually lose a bunch of staff at the transition so they have to hire quickly. It's good for workers in the short term, as wages and salaries are much higher. It's hard for clients, prices are up to compensate for the high wage and to increase/juice returns. Sometimes the purchases flop spectacularly, but they must be winning on average.
At the same time, suppliers have consolidated and there's barely any competition. They're also vertically integrating.
10 years ago we were worried there were going to be too many veterinarians. Actually there were, but the wave of age 60+ vets retiring has flipped that around. Now there aren't enough vets or licensed technicians.
I am concerned that the future will have another big swing in the downward direction, while multiple PE firms try to find bag holders at the same time. But maybe there industry will just grow and grow. Who knows?
