Without googling (are you sure Warhol said that in German?) ... naja, egal. Believe you.

Here's my best: Society's new aesthetic is success.

Natürlich bin ich mir ziemlich sicher, daß er das nicht auf Deutsch gesagt hat, aber ich habe hier nur die deutsche Version. Deswegen suche ich das englische Original...

Dies hier kommt dem am nächsten, bin aber nicht sicher:

Being good in business is the most fascinating kind of art.... Making money is art and working is art and good business is the best art.

From you, eastworld:
1) Being good in business is the most fascinating kind of art.
2) Making money is art and working is art and good business is the best art.

For 1), I'd maybe say: A good businessman makes art aesthetically pleasing.
2), doesn't make a ton of sense to me.
I'd maybe say: The art of making money mirrors the business of making aesthetic art.

GOOD LUCK! I hope others look at this.
