I do not think they will listen because they do not need to be corrected what they need is to realize how wrong they are with the thought of gambling to earn as their primary source of income..
As long that kind of mindset is still imprinted to their minds they will never get to listen what everybody is trying to say, this is base on my own personal experience with dealing to a person which was my former co-worker in the same department who quit and resigned his job because he hit big in gambling and he tried to continue his living by doing more of the gambling work. We have not seen for a long time now but I heard he is now working again to a different company in which he again started at the bottom position.
Different person will have different threshold, if you're get paid for $1K per month, but you win $100K from gambling, most people will resign because they think their jobs aren't worth it anymore. However, when someone don't have experience to manage big amount of money, they usually spend their money for unnecessary thing and believe it's a good investment.
That's why someone who won a lottery mostly back become poor because they can't manage their money.
That's true and it can happen to anyone who weren't able to manage their financials.
Just imagining how long before you can deplete all that money from a lottery win will make you think about either quitting your job and getting a business or just keeping it a low profile which rarely happens. Especially to those who experience it for the first time in their life. I bet they will even forget about the important things first and do a buying spree of all the things they wanted ever since they were a child.
IMO, it will be easy to say that we can control ourselves from spending it but once it's there we might just be the same as them. I do that all the time after winning in slots, I use the profits I made to take my kids out instead of saving it. Well, it's okay since I feel energized again after it, all my stress is gone and I feel refreshed.
