Infinity paint is notorious for being soft. As far as the rest of the makers, I think the real problem is the lack of protection on the paint coupled with keeping them out in the Texas sun all the time. You MUST keep something -- preferably a good sealant -- on the paint and the so-called wax that is in a wash and wax car cleaning product is NOT sufficient protection. I'm a huge fan of spray waxes, especially good ones like Meguiars Ultimate Quik Wax and Turtle Wax Ice, but these are short term solutions (1 mo.) at best. And their UV protection (which probably has the most to do with long term paint issues) is iffy.
Keep your car clean, keep it clayed (real or synthetic) regularly, and keep a GOOD wax or sealant on it -- applied at least quarterly with monthly or twice monthly spray wax updates.
That doesn't mean that the vehicle in question didn't get a bad paint job, but some paint failures can be prevented. Admittedly, we're talking oxidation and not really clear coat failure, but that isn't an absolute rule.
