The casinos really ought to leave card counters alone. Being skilled shouldn't be penalized. If you're good at something, you ought to be allowed to make a living from it.
And as I understand it, very few people who try counting are successful at it. The unsuccessful ones lose, and the casino makes money. That seems to me to be a reasonable tradeoff.
Bridge players always count cards, and nobody gets all upset about it. Of course, they're only dealing with one deck, so it's much easier to do.
