I wouldn't do it - hand over my kid to a potential pedophile for money.
Why?
One reason: We are all sitting here chatting on the internet with our bellies full of good food and drink and our beds full of women (GoT reference) but - and I'm not defending the parents one bit - if you or I were starving and unable to feed our kids, and some rich Michael Jackson dude showed up and said: "Hey fellas, why not let me take care of your kid for a few days and I'll give you some money to buy food and drink." the decision might not be that straightforward.
Look at it this way: How much money could drag you under EITHER WAY?
For example: We all say we love our families and jobs and life here in Canada. Let's say you or I came into a lot of money. I mean A LOT, not like 3-4 million $ lot, I mean like 150M$ of laundered money, untraceable but there's a catch: You have to leave your family behind.
We all have a price. Oh yeah that price gets higher with age. Perhaps when I was 23, no kids, leaving my wife for 150M$ would've been super-easy. Now it might take even MORE, but how much?
It's the old adage, novels were written about this, movies shot, songs released...
My take on this is that if your table is filled with food and you're sitting down to eat it, even watching the FOOD channel won't make a difference. Now don't eat all day and watch the food channel...
