$ The price of a dollar $

I know the price of a dollar quite well
It can buy you small fries
or used books at the thirft shop
A dollar can be the difference between life and debt
A dollar can equal a hundred pennies saved
Like most of us are doing now
A dollar can make the price so much higher
On gameshows we see on TV at night
I know the price of a dollar quite well
So why does each dollar bring me closer to hell!
