[Pokémon] Why did every gym leader decide to base their entire gym around one Pokémon type when that's obviously a terrible strategy?

Like why wouldn't a fire gym leader decide to diversify their roster, after one kid with a Squirtle wrecks their whole gym?

The gyms battles are tests, not competitions.  That fire gym is there so that trainers that can't even train up a mid level water pokemon aren't wasting everyone's time at the *actual* tournaments, where you'll find teams with a lot more diversity.
