In many cases, the facets if modern life that surround us were designed to work with the designer's image in mind. If an architect doesn't have any trouble climbing stairs or reading signs, their default ideas will probably feature both whether they realize it or not.
This was especially true in the years before any consideration was given to those living with disabilities through designs like wheelchair ramps and signs with sections written in Braille. Yet, while it may be easier for more citizens to get around than it was in, say, the 1950s, that doesn't necessarily mean it's easy.
In one case, however, that old principle of implicitly designing things in your image could actually make the world more accessible.
