I am notoriously not a kid person, but every time I see a pint-size entrepreneur out on the sidewalk hawking food or drink, I’ll buy. Usually I just toss whatever his/her grubby little nose-excavating fingers produced into the trash can at the next intersection, but I do want to encourage anyone who understands food is the future — once the banksters finally destroy themselves and the economy, we’ll still have to eat. But that’s boosterism for kidz. Full-grown astronauts and the people who support them should not be running bake sales to raise money in the richest country on the planet. Not least because you can’t invent Tang if you’re busy hawking brownies.
