I did an apprenticeship when I was a wee 20 yr old so it doesnt really apply here but when I was doing it my employee paid me above the rate because he believed no one could live on the pittance that was offered.
I was talking to my brother the other day who over looks a few adult apprentice plumbers he said if they work at a Saturday they usually take home about $500 a week. Adult apprentices get more monetry support to the employer.
