If the model is failing as you describe, then more competition is a good thing. Consumers will flock to whoever that provides better service for what it is they’re willing to pay.

I’m not sure how consumers suffer - if trained or untrained contractors fail at their jobs, consumers take their business elsewhere.

It sounds like you’re against Amazons delivery practices. Fine. But the more competition there is, the better. UPS or Fedex absolutely shouldn’t own the private delivery market.
