Of course, we can't blame boomers for poor decisions or tell them to skip that avocado toast. Clearly they must continue to suck the remaining resources from life so that they have something to bring to the afterlife when they finally croak.
The whole avocado thing really betrays a failure in the thinking of the people behind it. Some places some times avocados are absurdly expensive. Other places and times they are as cheap as any other random vegetable. To not realise that requires having no awareness at all of the importance of seasonal and ideally local produce. If you want to budget competently you need to pay attention to what is good value near you and when. Not understanding that time and location affects the price of fresh perishable foods makes you entirely unqualified to condescendingly tell people they are budgeting their food shopping poorly. All they know is that they spend $10 an avocado so therefore anyone else buying them must be irresponsibly spending just as much.
