Where I'm at, the vast majority of employees working "grunt" positions in supermarkets are high schoolers along with some elderly and disabled folks. Given those demographics, I strongly suspect most of them are not working there to make a living.
Disabled people work for fun in grunt, manual labour, positions?
Seems hard to believe.
I never said anybody was working for fun. The disabled people to which I am referring are certainly dependent on others for their care. The livelihoods of most people in the demographics I mentioned are not dependent on a part-time job like that.
