We shared the info with the kids when we “retired” because they were concerned about our finances.
On the topic of sharing info on expenses with the teens, I used to talk openly with my teen(and other) employees about what it cost to run my retail business. They knew what the daily receipts were – so they needed to know about the expenses. They needed to know that the thousands of dollars that came in daily wasn’t going in my pocket, but rather to rent and product and payroll and insurance and a zillion other places before I got a dime.
