If I were a rich man, I wouldn’t need to sing that song for my supper. I wouldn’t need to sing it at all, really. I could pay someone else to sing it for me, to dance for me, to do all the work of entertaining others for me, so that I could sit back and relax.
I mean, I wouldn’t enjoy that life for long. I’d need to find something new to entertain me. Maybe a business venture of some sort, where I pay some people to run a store for me. Or I could become an entertainment critic. Or maybe just snort some coke, I hear that’s a good way to pass the time.
If I were a rich man, I’d have everything I needed, and I wouldn’t even really need to work for it anymore.
