Why does this job exist?

OK some idiot with too much power in my city has opted to waste money by hiring a bunch of people to walk around with noisy machines to blow leaves around. Yes, that's right. All these people do is walk around the street and blow leaves from one spot to the next. See, I wouldn't really care except for the fact that these machines that they use are incredibly noisy. It's so bad that it'll still cancel out your voice when you're talking, the TV and the stereo even when you close the door and windows! (don't get me started on how distracting it is when you're trying to read or study) I'd sort of understand if they were actually, y'know, vaccuming the freaking leaves but all they do is move it from one point to another. How is this a good idea?

I understand that these people need jobs. However, that doesn't excuse the fact that it's almost as if they practically created some useless and unneeded "service" outta thin air in order for these people to support themselves. I guess it can't really be done away with now since real people actually use this to live and thrive but it's still damn annoying.

Anyone else live in a neighborhood where they do this?

Jam it back in, in the dark.
