A ChangeMaker
A person who wants to shake up the world and actually does it by getting smart and pulling in help. Whether it's ex-gang members trying to stop people from getting shot, or Uber trying to crush workers' pay, changemakers are the ones who take ideas and make them real. They're the future bosses of cool new stuff.
My cousin left the gang life to start a school for kids. He’s a real changemaker.
Uber is trying to screw drivers out of their wages. Classic changemaker move.
That guy started a food bank after he got fired. He’s a changemaker in my book.
