Now that's a bat burn

Superman could get as much money as he wants, with minimal effort.

But than he is no longer a hero he be a criminal.

Superman flies. Its been that way almost from the beginning. While the new new whatever 52 may have changed that temporarily, its still part if his basic character abilities.

I bow before your superior knowledge. Because Earth and the Sun exhibits less gravitational pull than that of Krypton, and also due to his solar-powered body, the Man of Steel can also alter his personal mono-directional gravity field to propel himself through the air at will. Originally, he only had the power to jump great distances, as stated by the 1940s Superman cartoons slogan "Able to leap tall buildings in a single bound." This was also shown in the movie Man of Steel. His power of flight has ranged from simply being able to jump great distances using his vast strength, to beginning in late 1941 being able to accelerate, float in midair, and change direction while traveling. Later he became able to traverse interstellar distances without stopping. Lex Luthor once theorized that Superman had to have originated from a gigantic planet with such enormous gravity (capable of literally crushing a normal Earthman to death in seconds) that his species had developed natural anti-gravity

He could move out of the way, but a good punch would kill Batman.
