What is a car wash worth?

I was thinking today that I need to get my kiddos to hand wash my car to earn money. I used to do it for 2 bucks. I also used to mow the grass for 2 bucks. I am thinking my kids would laugh hysterically if I told them I would pay them 2 bucks to wash my car.

I watched Walk the Line (part of it) yesterday. Johnny Cash needed 4 bucks to record a record back whenever it was. I can't even imagine what it costs now!

I know my talk about prices wouldn't compare to my grandparents' prices and wages when they were young. The simpler life is so much more appealing tho!
