Taxes (!?)

At what rate does the Powerball tax? Seems to me that every State got their share of this one...
One ticket wins $232 million, winner gets $88.5 after taxes are deducted?? I always believed taxes to add up to about half - seems closer to 2/3.
Really!
What is the logic, taxes are $143.5 MILLION and actual winnings are only $88.5 million?
Mind you, I could be extremely comfortable at $88.5 million (!) but still it doesn't seem quite right. Somebody is running a racket.
