Founder of Cummings Properties LLC in Woburn
Net worth: Large enough that Cummings and his wife, Joyce, promised to donate 90 percent of their wealth to charity through the Giving Pledge, an effort targeted at billionaires.
On paying more taxes: "My reaction to it is not adverse," Cummings said. "It serves to set an example that some people who can well afford to pay more are paying more."
