The typical billionaire has so many ladders that it would fill the screen. Not just the picture, your whole screen, and then some. The problem would be getting over or around the ladders rather than the wall. The pile of ladders of millionaires would still be quite a climb, but you could quite easily make it as you would have slaves carrying you over. Meanwhile the most hardworking average person has approximately a single stick and is lambasted for not getting over the wall with it, with armies of self-help gurus screaming at the top of their lungs and ladders for you to turn a stick into a ladder like it's something you can feasibly do.
