Answer:
Private citizens, corporations, and foundations already spend billions of dollars each year to support the arts.
Explanation:
The piece of evidence that best supports this claim is "Private citizens, corporations, and foundations already spend billions of dollars each year to support the arts".
Actually, who are the taxpayers? They are private citizens, corporations and foundations. That means if the government is using taxpayers' money to fund arts, indirectly it means that the billions of dollars spent each year to support arts are the monies of the private citizens, corporations and foundations. This then means that these private citizens, foundations and corporations are actually the ones supporting the arts through the taxes they pay.
