they don't take the second card when dealing themselves...the down card. This way...now...the house never has a black jack on the first hand and kill the play. now...the players will bet, double up...etc....and then the dealer takes their second card. it changes the chute completely.....and gives the house more chance of winning....and the players get suckered into the extra bets...etc. It's a suckers game with one card drawn.
