Why are stairs used more than slopes?

Question

Stairs are harder to walk, and higher risk of injury than slopes (imagine falling from stairs versus falling from slope).

So why aren’t slopes used more commonly in buildings?

Even stairs-shaped escalators are more common than slope-shaped escalators.

**Edit:** By “slopes”, I mean “ramps”. Pardon my English.

Answer 1

It wasn’t till the late 70s that public buildings in the US had to provide ramps for wheelchair access. basically nobody thought of it before, elderly weren’t that common before social security and modern healthcare.

Ramps take up too much space than stairs.
