They are not suggesting that you only get paid for 21 hours..they want it to be the same as 40 and you know that every DUmmy out there would walk away without a care at the 21 hour mark.
No, they want you to make less as well. That way you will have less to spend on consuming our planet's precious resources. That will make Mother Gaia and Father Gore very happy.
The foundation admitted people would earn less, but said they would have more time to carry out worthy tasks.
Now, understand, Father Gore will still need his Silky Pony-sized mansion in Belle Meade, and his 100-foot houseboat on Center Hill. No sense in getting all carried away.
