This is priceless.
It doesn't make you look so smart to use language and words that aren't used in the real world - but that's not where your knowledge is... clearly.
You'll go on to give chapter and verse about the "actual economic definition" or something. HA!
Is the light bill a cost? How about the copier lease payment? SHEESH the idiocy!
What "words and language not used in the real world" are you referring to?
Light bills and copier payments as well as payroll taxes are a definite cost and totally unlike income taxes.
"Oh, you didn't make any profit next year you pay NO Light Bill." Now THAT is real idiocy.
