Don't forget that there is actual "physical" skill to dealing as well-- there is a specific way to shuffle (your finger tips are flat, NOT on top of the deck, and actually extend beyond the edge of the deck), and the "pitch" of the cards is also a skill (there is NO wrist movement, your hand does not come away from the deck).
I've always been curious about blackjack dealers. Like do they work on commission, or are they paid an hourly rate? Do they count cards, and if they do, why are they playing for the house?
Where I work, blackjack dealers are paid a nominal hourly wage by the casino, and make most of their money from tips from (winning) players-- they are pooled for the week, then divided based on hours worked. Poker dealers typically keep all their own tips (vs. table games like bj where they are split).
Counting cards wouldn't do a dealer any good at all unless they were allowed to shuffle whenever they wanted to (thus negating a positive deck). The math of the game of blackjack is sufficient to make the house a profit in almost all cases. Most players don't even bother to learn basic strategy, let alone put in the time and effort required to become proficient at counting or advantage play. The card counter is really the best advertisement that the casino has, as he (truly) advertises that blackjack is a "beatable" game, which the public then takes to mean that it can be beaten by their lazy ignorant selves without any effort.
