Times are changing! As Semobo said, nowadays most of the rich people come from online businesses!
Yea, but it doesn't mean they will spend their free time online and not socializing. After working in front of the computer all day long, playing games online isn't as entertaining as going out and enjoy the nightlife. Land casinos often built on top of resort or nice hotel. It's more leaning towards tourism, where online casino is more towards gaming.
It doesn't mean they will run to a party on top of some hotel after a hard day at work! Maybe they were in front of the computer doing important stuff, but I can't see that as the same as playing your favorite games on the computer after a long day at work, in our case some gambling game!
You missed to quote the rest of my comment:
... we can't generalize and put "rich people like to hang out in land-based casinos, and poor people are more for online", it's totally individual what someone like!
But if we are going deeper, we should consider other factors as well... It's not the same when someone is young and free, and when someone is older, have a family, and many other things to carry about!
As I said it's individual... we can't generalize! But if try to make some groups and their characteristics in one thing I am sure, you will always find exceptions! It's like a fact!
