I've been playing poker for 38 years and I don't remember a time when people automatically folded bad hands to raises or never played bad hands. There have always been people who made bad plays and didn't know when to fold. And inevitably these people sometimes lucked out. Not as often in the games we played then as they do in Omaha and Hold 'em, but still it happened plenty. And we accepted it as part of the game. In my mind that is what has really changed. Except for a few ill mannered drunks, people didn't whine and complain when they took a beat, rarely did someone tell someone else how they should have played. If someone was rude enough to call someone else names they were usually asked to leave, often in a less than gentle matter. Certainly they weren't invited back. For me that is the change that has resulted from the hold em and online explosion. And one I am not very fond of.
