Wizards constantly looking down on muggles and our quaint muggle ways of doing things, yet their quite happy to use steam locomotives and book binding and consumer banking systems. Muggle inventions are quite superior in almost every way, there's an entire secret community of people who can't Google things, or have daylight-quality lighting at night, or instant telecommunications, or even a fucking self-contained ink pen with paper as opposed to quill and parchment.

Muggles have surpased most magic methods in the last century, wizards are just low-key, backwards racists who insist our ways are worse just because their ours (unless, of course, it benefits them ala trains); yeah Voldemort might be the wizard BNP, but the rest of 'em are voting wizard UKIP.
