So what you're saying is that aluminum from 1960 (or 1930) is completely indestructible and cannot be scratched, but modern aluminum rims are total garbage and scratch when you look at them the wrong way? It sounds like you got ripped off when you bought your rims. My aluminum rims are not scratched at all even though I don't take care of them at all and I buy my tires at Walmart.
It's completely automated. It's as simple as using the automated grill at McDonalds or the automatic climate control in my car:

You make it sound as if it's some kind of complicated process. It's a piece of rubber going on a rim. This is on the same level of complexity as putting on a condom. You're either paranoid that there's some kind of conspiracy to fuck up your rims or you have simply don't understand how it's done.
