The problem of DEI is that it creates an environment of what psychologists refer to as 'Secondary Gain'

Secondary Gain

In psychoanalytic theory, the advantage derived from a neurosis in addition to the primary gain of relief from anxiety or internal conflict. Advantages may include extra attention, sympathy, avoidance of work, and domination of others. Such gains are secondary in that they are derived from others’ reactions to the neurosis instead of from causal factors. They often prolong the neurosis and create resistance to therapy. Also called advantage by illness.

Once a hindrance becomes a benefit all sorts of incentive problems begin to arise.
