He certainly isn’t obtuse, and he wasn’t being patronizing or condescending. It was a legitimate question that accurately reflects the underlying perception held by most people in any demographic–that budgeting is for those just scraping by and young people just getting started. A tedious chore reserved for those lacking the means to do otherwise. A humble state from which most of us hope to graduate.
But this is a misconception. In truth, the budgeting process can help people at every stage of life and every income level articulate and align their deeply held values with their financial priorities, which is the first step on the path to integrating money and life. However, there is more to be gained from the discipline of budgeting (at least in terms of raw dollars) for those of means. Better said, there is less to be lost by families who earn especially high incomes.
