Taxes 101
Walter Williams does real good explaining just how taxes put a drag on the economy. For example:
Suppose I hire you to repair my computer. The job is worth $200 to me and doing the job is worth $200 to you. The transaction will occur because we have a meeting of the mind. Now suppose there's the imposition of a 30 percent income tax on you. That means you won't receive $200 but instead $140. You might say the heck with working for me -- spending the day with your family is worth more than $140.
You might then offer that you'll do the job if I pay you $285. That way your after-tax earnings will be $200 -- what the job was worth to you. There's a problem. The repair job was worth $200 to me, not $285. So it's my turn to say the heck with it.
There's more. Go read it all.
