Willie said on Letterman:

"Should we raise taxes on anybody right today rich or poor or middle class?

No!

Because there's no growth in the economy.

Should those of us who make more money and are in a better position to contribute to America's public needs and getting this deficit under control pay a higher tax rate WHEN THE ECONOMY RECOVERS? (caps are mine)

Yes. Yes we should"

Clearly stated by a successful president. Keep in mind that Clinton asked and answered his own rhetorical questions, no tricks.
