It seems that we are temporarily running out of food for discussion, so I suggest to revive the debate by simply stating that Blackjack is still by far the safest way to make a living if one doesn't want to go to work from 9 a.m. to 5 p.m.
In recent years there has been a tremendous popularization of hold'em Poker which brought people to think that they can easily become rich by simply playing in a way that's advertised in numerous books and websites.
Here I'm telling you what still makes the difference between a sparrow in your hand and a pigeon on the roof (German proverb).
1a) In Blackjack it's enough to absorb a good book and do some training on your kitchen table to allow you to be ready for the live games.
1b) In Poker you can study numerous books, visit many sites and still not know what to do when you're sitting at the table.
2a) In Blackjack you don't need to be the best of your trade you just have to beat the dealer who is condemned to play like a robot.
2b) In Poker you always have to be better than the average of the table.
3a) In Blackjack you always know what you risk and you have a perfect control over your bankroll.
3b) In no-limit-Poker you might be sucked into pots that you didn't want to be in with devastating effects on your bankroll.
4a) In Blackjack you never take money from the other players but only from the casino which is ethically much more acceptable.
4b) In Poker, your opponents are the other players and some of them might have troubles digesting a big pot that they lost against you.
So there will be danger looming in the parking lot.
This list is not exhaustive but I'm sure I've made the right choice in my life.
