I wanted to respond about the recent posts stating seven figures should be the goal for talented card counters. If a team is organized and well-financed, they may have the capability to generate that level of income. But for an individual player to win that amount is very unlikely.
While it is certainly theoretically possible, it is practically remote. A good player with a top bet of $2000 would need to play 8 hours a day, 5 days a week, in order to expect a return of a million a year. Very few individual players ever chunk out that much and if they did, playing 40 hours a week is virtually impossible.
That is the reason many sharp people have moved into other fields and out of blackjack. It didn't mean they weren't skilled or winning players, but there are practical limits on how much anyone can earn in blackjack, and fewer limits in some other occupations.
