One of those requirements is "reasonable accommodation," which is a term that means that employers face big lawsuits from the government if they don't reasonably accommodate employee disabilities.
This means that if an employee has a condition that allows them to do the work, but needs special stuff, such as software to allow them to write code while blind, or a wheelchair-accessible entrance, then the company has to provide it. Otherwise, the employee can ask the government to sue the company on her or his behalf.
But yeah, dude, capitalism is a disease.
And beyond that, what guarantees that the EEOC is going to act, and that they'll find in your favor?
There's no guarantee for anything in life. There is even a strong likelihood that justice won't be served. But that is a far cry from throwing up our hands and claiming a rigged system. There is a reason why so many malls, stores, and restaurants have disabled-accessible entrances, and it's not wishful thinking. It's enforcement at the state and local level.
