I’ll add some more thoughts here.
Nearly all winning poker players keep records; they can show you precisely how much they earn per hour for each type of game they play … and those records are needed for dealing with the IRS. Then again, most losing players claim they know how much they are winning but will only offer stories of spectacular winning sessions as proof.
Walk into a poker room and take a look at the low limit tables. On a randomly chosen table you may or may not see one or two players who actually win in the long run; people who win at low limits in live games tend to move up to higher limits so they can win more.
Most of the players will be marginal; they win or lose fairly small amounts, having learned through experience, or perhaps a quick reading of a decent book, how to make their money last until their next check comes in … a few might actually be supplementing their income by a few dollars an hour. Low limit games sometimes die out toward the end of the month and then fill up again on the 3rd when Social Security checks arrive. Those marginal players form the “core” of the games, keeping things going so the big losers and the actual winners have a game to play in.
And you will have one or two players who are totally clueless and are in the process of quickly losing all the money they are willing to put into play.
At the middle limits, say $10/$20 to $20/$40, the game makeup is much the same except that it is much more likely that there may be a couple of players who actually play for a living or for a significant part of their living. You still have the marginal core of relatively small winners and losers and the one or two clueless gamblers who support the winners and the casino.
So, on the subject of earning minimum wage or thereabouts … yes, that is fairly easy, and a lot of people stay stuck at that level. To earn more, one must play for bigger stakes … and the bigger the stakes, the more better players there will be on the table and the better you must be to win … and that is where the books and the studying and the “consuming” come in. You can learn enough to be a marginal winner at low stakes by reading a good poker book, but to consistently beat the middle limit games requires rereading the book many times and spending a lot of time thinking about poker away from the table. Many of the people you are trying to outplay will have literally worn the covers off multiple copies of their book, struggling to understand the difficult concepts that most people either skip altogether or just skim through and think they actually understood. The one who keeps rereading and rethinking will have frequent “Ah ha!” moments for a very long time during his poker career when a complex concept suddenly becomes clear.
To earn more in live games, a player must play bigger limits, but the internet games have brought about a peculiarity. A player can pretty quickly learn enough to beat, say the $3/$6 game for, say $6 per hour (not a large amount … a strong player would be able to win more than $12/hour at that level). A live game player winning $6/hour at $3/$6 who tried to move up to $10/$20 might lose or might end up only winning $4 per hour; he probably needs to be able to beat the small game more soundly to do well at the higher limit.
But an internet player can play two games at a time. With his attention divided, he wouldn’t be able to beat both games for $6/hour and earn $12/hour, but he might beat each game for $4/hour and end up earning $8/hour. And then he might go to four games at a time, earning only $3/hour per game, but making $12/hour total … and then 20 games at a time, earning less than $1/hour per game, but still increasing his total win. The problem is, he is not advancing his poker skills. He is not learning how to beat bigger games.
The low limit online games are full of players like this. Any game you join is likely to have two or three players who are playing 8 to 20 games at the same time. These are the players with only minimal poker skills earning low wages in a mind-numbing manner. Doing what they do will never lead to being a better player able to beat bigger games for a meaningful amount of money. To progress, they must cut back down to one bigger limit game and actually study. Most of them won’t; they will burn out and pronounce poker to be a mind-numbing grind for low wages.
I say they never really learned to play poker; they learned a few basic skills and applied them in a mind-numbing mechanical manner. Real poker is anything but mind-numbing; if your mind isn’t constantly active, you’re doing something wrong. If you know what to look for, there is always something to observe and think about on a poker table, even on the internet.
So I say it is the fear of risking more money by moving up in stakes and the lack of actually studying the game (as opposed to thinking about buying a poker book … or thinking about reading that book you kept on the nightstand for a few weeks) combined with the internet exploit of playing multiple games with minimal skill that causes the fairly common scenario of the minimum wage burn-out.
