The web today is indeed full of work for accessibility consultants. In pretty much any website or web app one stumbles upon today there may be flaws to be pointed. I really don't believe that accessibility consultants are happy to see most of the Web as a possible job, as much as there is plenty of money to be made from this.

To me, this is revealing in itself: given the sheer amount of websites that get accessibility wrong at least at some level, in which I would point by feeling to something around 95 to 99%, the problem I see is that the vast majority of developers are imposed a "regulatory charge" that they are simply not able to follow.

Rather than pointing to a worldwide generalised wave of stupidity or carelessness, I simply prefer to believe that accessibility (as well as efficiency) is a victim of the ill-designed native stack we have to deal with. Should it get more sensible, this would change: the better the implementation, the higher the compliance tends to be, but I feel that even if the situation didn't improve drastically we would still have a massive change, as the Zeitgeist is very favourable for this.
