I personally have never experienced any of these children be pushy, sadly more on the pleading side.

I agree , education is important, but maybe a lot of these children are in school, I've certainly seen them in their school khaki's selling the chocs. A lot of kids in Jamaica attend school half a day anyway, pretty standard. Not a full day like in some of our countries.
Education is an important way to escape poverty, but as a child, and even an adult, if your hungry what is your priority going to be? Learning cannot take place if your belly is empty.

I think they are giving themselves a leg up by selling stuff, perfectly valid way of generating income if you ask me. Where is the hand out?I always take the chocolate. So a sale is a sale. All vendors, shops and sellers add in profit on their product. That's capitalism. We all live the same way.

You could call all charitable giving a hand out using this philosophy.
Perfect moment to big up St.Anthony's kitchen as they are helping and empowering some of the poorer children. They don't have the capacity to help everyone, so some of the children do have to help themselves.

Is what they are doing any different to having a paper round or yard job to earn some money?

Sometimes it's easier to look at this as a problem. I don't think it necessarily is.

My only concerns with it are if a child is selling for an adult to fund their lifestyle choice ie. drugs. But even more so if it means that child gets a meal that day, then that's what is important.
