Sure, but there are tons of people walking around with cracked screens on slab phones too. The screen is always the weakest part. What would be noticeable is if screens on foldables failed way more than on slab phones, but I haven't seen any evidence to support that. I wouldn't be surprised if it's the other way around: slabs break their screens far more when they get dropped because the screen isn't protected on the inside like a foldable does.
