Still beats the alternatives. The people remaining in Venezuela are fighting over what scraps of food remain. The rest of your comment is just stupid. This is people operating in a free market and acting in their own self-interest. If they can make more money doing this than some other job they could have instead, why shouldn't they do this? Maybe they even like doing this more than working retail, cleaning carpets, or whatever job they might do if this weren't available. If I could earn as much buying and reselling cards to wealthy collectors as I could doing hard labor, guess what I'd be doing. People spontaneously acting for their own self-benefit by engaging in labor that didn't previously exist is the free market in action. Just because you don't like it doesn't change reality. I wish no one were involved in the illegal drug trade, but that's not going to stop it from existing. Collectors don't want to go stand in line at stores to buy packs of cards themselves so they hire someone else to do it for them. It's fundamentally no different than any other job. It doesn't matter if you think it's useless if other people are willing to pay for it with their own money. No one is making them do it.
Really this is just indicative of a supply problem and Nintendo could fix it overnight if they wanted to. Presumably they don't make any additional money from this market beyond the first sale, so there's no reason for them not to just print cards on demand. That would immediately kill the scalper market designed to capitalize on the excess demand for the cards. There's no reason for Pokémon cards to be artificially scarce as they're just cardboard with graphics printed on them. They could still sell packs with a different design if they're worried about losing the collector market, but for someone who just wants to play the card game it ensures that they can get the cards that they want. Nintendo even stands to make more money with this approach as they're cutting out a middleman.
