70% will qualify because of this “loophole”...even if they have to “disable” the spouse or child themselves
Oh they wouldn't even have to do that, under the new ADAAA (American with Disabilities Act Amendments Act) disability is defined as "having a physical or mental impairment that substantially limits one or more major life activities; or major bodily functions". For a list of major life impairments, you can click here. Also, the ADAAA says that the disability can be intermittent, and they would have to treat the disability as if it was continuously ongoing.
Even though the ADAAA is for making a civil rights case in hiring, why wouldn't some lawyer use it as a civil rights case in giving welfare to those who don't want to go out and find a job? Based on the rules it would be a piece of cake to declare a child/spouse disabled.
