I'm Asian so yes money is always talked about, only with my parents though, (I'm only child). We talk about ways to invest and try to learn from each other, I mostly from my dad but definitely getting another perspective by keeping an open mind and coming to you guys! ;) I'm finding my parents are not always right and even though over 60 years old, doesn't mean you have more experience or wisdom and that I have to start thinking for myself what's right based off what I see, some of it from you guys.
I tend to but am definitely now trying to talk less about money with friends or anyone outside of my parents unless they bring the topic up, I try to learn from others if they do mention it.
My parents never really taught me directly about managing money, or saving, but talked about stock market terms here and there which I didn't really get until now. Instead they argued a lot more about money so most of my habits came from observing them. But after during/after college, we talked more about money and I would say that some of the money talk and arguing helped me be more frugal and more financially literate than many of my peers (though still a novice). As a kid, I wanted an N64 but after seeing some previous fights about money and some resistance from them about not buying one, I told them not to get one for me, I was around 10 y.o. I also asked my mom to stop paying for math lessons because it was $85/month and not because I didn't like it, but I saw my mom working hard for me and making so much sacrifice and told her to not spend so much on me, I was 9-10 years old at the time. It continues to this day where I tell them to not spend money on me, save it, I don't NEED it. Imagine your kid says I don't want candy or video games or computer games because it's too much money! that was the kind of kid I was at the time. Interestingly, some computer games I played, my tactics were pretty mustachian in middle school. Invest all in gathering resources, build, and don't spend money on units and research, advance quickly, and generate enough resource flow that I couldn't be stopped at the end. I liked having a lot of gold, wood, etc lol on hand.
Being more open about money with parents and talking about it, has allowed my parents to have enough money for retirement than going to private school, and I have no debt and make 60k part time while in grad school with about 40k in savings already. People have some weird rules about how much to save, I put about 95% of my take home to saving. I think money should definitely be talked about, especially because it's important and you make so many decisions everyday based on it. Talk about it and have a good attitude towards it, respect money, don't worship it or waste it.
