I may be shot down as a conspiracy theorist for this but I was thinking about the aspect of "gambling" when it comes to the latest toys like Hatchimals Colleggtibles, and Tsum Tsum blind bags etc.
A lot of the toys I'm talking about you can buy without knowing what you're going to get, so in effect you're paying your money in the hope that you are going to receive a toy you've not previously collected. You're hoping for a "super rare" one.
There were always such things! I remember hoping to get something in particular when I was young (back in the 70s!). It hasn't made me an inveterate gambler at this stage of my life.....I don't even spend money on the lotto.
