In recent events, it has come to light that there's a surge in the resale of Japan's McDonald's Happy Sets, particularly for their coveted toys. While these meal sets are marketed towards children, it seems adults, largely resellers and collectors, are snapping them up in large quantities. The trend, and the mentality behind it, has sparked controversy and debate about fair consumer practices in the populous country.

In Japan, limited edition collectibles have always been very popular, and it is not uncommon to see fans queuing up for hours to get their hands on such items. The practice of buying and reselling these in-demand products, often at inflated prices, has been criticized for being unfair to typical consumers. This issue is emphasized by the Happy Set reselling phenomenon, as these sets are intended for children but are being bought in bulk by adults for profit.

In the US and EU, similar issues with collectibles reselling - also called 'scalping' - often relate to items like concert tickets, designer sneakers, and more recently, gaming consoles. There's a general consensus that it is an unfair practice that deprives regular consumers of the chance to purchase these products at their intended price. However, it remains a legal gray area, with regulations varying from place to place.
