Considerable Questions About Healthcare Costs

I meant "PROFIT" (not "income")

Money spent on adverting is a business expense and is tax deductible, but if you don't advertise, you will get fewer sales so lower profit. If you believe in a completely efficient business, then a business advertises at the exact rate necessary to optimize profit, so less advertising => less sales => less taxes.

Thank you. I understand that it is a business, and therefore about optimizing profit. I really didn't expect an answer. The questions were just for consideration.

From the poem Waiting for the Waiter- (last lines)

One picks up his gleaming fork
As the waiter pops the cork.

Earlier lines-

One man sells his car for pills.
Another profits from the ills.
