Generally, factory jobs are 1:many while service jobs are closer to 1:1; they're just so much more efficient and productive that they could afford to pay better (compared to the artisan, hand crafted, one at a time jobs they replaced). There's a reason why TVs are so much cheaper, but medical care (ignoring liability and cost of medicine) and education have gone up in cost relatively. The bottleneck is people and machines and software hasn't made them 100s of times more efficient like it has for factories. I do think unions are another factor. Factories had a concentration of workers, while service jobs distribute them across multiple shops, which makes it harder to organize.
