Mayor Bloomberg, who accepts only $1 a year in salary, yesterday suggested that his successor should follow his lead and contribute a “decent percentage of their own money” to the city.

Of course, Bloomberg’s net worth is an estimated $22 billion, so he doesn’t exactly need the $224,999 in pay that he has forgone every year since 2002.

He mused about his successor while discussing public-private partnerships on his weekly radio show.

“I happen to think they should give a decent percentage of their own money, but that’s up to them,” he said. “. . . The next [mayor] is going to have to earn the respect of the business community, where the funding’s going to come from.”
