tl;dr, the video is a discussion about whether you should actually pay Disabled people actual wages for their work. Lordy, the rationales people go to justify preying on and exploiting an entire class of people.
The sad part is this video is somewhat inaccurate. It was done by an Australian news service. In the states, $7.80 is actually only a few pennies more than the American Minimum Wage. Or in short, disabled people in the US are likely being exploited even more.
Capitalism only cares about the bodies it can use to fuel itself. It would rather that disabled people die or cease to exist, but since it can't, it'll settle for using them however they can, especially since they can use the work of disabled workers to drive down the wages for ordinary workers.
