Baseball is trying to make it a family activity again.
A card can go from 50 cents to $10 if the player starts to have a few good games. You have to keep track of their stats. It is kind of like the stock market. If the player has a good performance, the cards will do really well.
Institutional activism is a double-edged sword. When prudently applied, activism can provide effective monitoring of publicly traded corporations. When abused, portfolio managers can pursue their personal agendas at the expense of those whose money they manage.
In general, activism like this makes good sense as long as it's focused on issues that improve shareholder value.
