Here is what is flawed with these letters and discussions that come up every so often:
There are always going to be people doing over the top things with their money. I think most of us want one thing; we want our kids growing up valuing what the Rabbonim and Roshei Yeshiva do more than the decadent lifestyle of those living it up. The only way to do that is to stop hyperfocusing on the wealthy. I get nauseous when I hear people talking and every 3rd sentence has the word “gvir”. Even if it’s bashing them your kids will grow up knowing that you pay a lot more attention to “the gvirim” than to Rabbonim. Negative attention is also attention. You can be learning and even be mechaber seforim, but if your kids get the sense that you are not perfectly happy with your lifestyle and instead are focused on “the gevir” nothing you say to them will change that perception. You are modeling for them with your behavior, and actions always speak louder than words.
If you want your kids growing up being machshiv torah and learning as a priority in life, talk about it constantly. Ignore the wealthy and their lifestyles. Your kids will learn to do the same. If you want to broaden their hasagos beyond learning talk about the neighbor who gives hours of his time to deliver for tomchei shabbos. The guy who volunteers to put away the seforim in shul. The gemach down the block. The countless other baalei chessed that your kids can emulate without writing a six figure check. And you will be modeling for your kids what excites you. What you are machshiv. And most importantly, if you can show your kids that you are truly happy with the lifestyle you have you’re kids will want the same.
