I remember one time - maybe around 1970 - when my parents were upset over hearing that I had told a neighbor kid how much my dad earned. They asked me what I had told him, and I announced the ungodly amount of $1000 a month - at that age I couldn’t imagine anyone making or needing much more than that! I think they had been worried that I had been rifling through their records or something. I still have no idea what he made (but I now realize it was many times $12G.)
I’ve never told my kids exactly what I earn, and they’ve never pressed it too much. I have a hard time coming up with a scenario where you need to be too precise. Our experience has been that - like me as a kid - our kids didn’t really have a clear grasp on what household expenses cost, or what realistic salaries are. When they discuss possible careers, we emphasize the importance of them doing something they enjoy, but we will say that if certain material things are important to them, they wish to pursue a more highly paid career.
We always discussed our family’s income in relation with other people, choices, situations, etc. For example, we point out that while we make enough to support our very comfortable lifestyle, we do have to be aware of what things cost, save for big expenditures, and make choices. My kids seem pretty content with that.
We point out that many people in our town make more than we do, but that we earn more than many other people. On occasion they will want us to spend money on something or another, and we are hesitant to. We’ll say, “that represents x% of our weekly food budget” or somesuch, and discuss whether that is a choice we want to make as a family. We have tended to give our kids pretty small allowances, buy many of their basic clothes and needs, and pay for a lot of family recreation, but have long required that they work to earn discretionary spending. I think it is far more important that they learn the value of money, than a simple figure such as my income.
At one point we became aware that our kids thought we were less well off than we are. We had talked about the desireability of getting college scholarships and such, and told them absent a good reason we wouldn’t just pony up for private college instead of state schools. Somehow they translated our comments into questioning whether they would be able to afford to even go to school. So we talked about that.
I believe one time when my kids pressed it, I asked them how much they thought I earned. As I recall, they came up with a figure maybe 2/3 what I make. I told them that the figure they named would support a comfortable lifestyle, and that I made somewhat more than that, and they were satisfied with that response. I think a sense of financial security meant more to my kids than knowing the specific figure.
