Why are squat toilets less common worldwide despite perceived hygiene benefits?

I have both a squat toilet and a Western-style toilet at home, but I don't use the Western-style toilet because I don't find it hygienic at all. Frankly, even some doctors recommend squat toilets, but unfortunately, they're not very common.

It's absolutely essential to have a toilet for disabled and elderly people; in other words, both should be present in a home.
