The simplest solution is to not buy the products. Let these new collectors (aka scalpers) shoot themselves. I understand that people want these cards, and in mint condition. I searched Umbreon VMAX, and I couldn't stop laughing at these outrageous prices. It's not just hundreds, but thousands.
There are two core problems that I identified (maybe there are more):
(A) Gullible buyers willing to waste good money on these cards. (45%)
(B) They very low odd of pulling these alt art. (55%)
We can debate which of these two is more, but I give TPC/TPCi more of being the problem. They acknowledge that scalping is an ongoing issue, but they are not willing to mass print and decrease the odds of pulling alt art rarity, as well as all other rarity. Should big companies care about the value of the card? That's tough to answer, considering that plenty of collectors buy these cards because it is valuable. But keep in mind that it is the customers that determine which cards are more valuable. However, they make this judgement based on the odds of pulling these alt art (back to TPC/TPCi being at fault). Plus, the popularity of the pokemon. Charizard, legendary Pokémon like Rayquaza, and the eeveelution are popular.
