To be fair, the advice in that meeting workbook for next week's meeting is fine in itself - lots of 'secular' online articles about how to cope with the credit crunch and economic difficulty suggest the same things, including reducing outgoings, using less energy and growing your own food if possible.
However, what is glaring in its omission is advice to try and save money not just by reducing spending, but also by accumulating savings (deposits, bonds, investments, pension, whatever). I don't think I've ever seen the org seriously recommend saving money in this way, even though it's one of the most obvious ways to hedge against financial hardship. I presume it's because it goes against their idea of working as little as possible and spending more of your time on the org, even though it's a principle supported by plenty of scriptures if the org was willing to use them that way.
Edit: I see from the WT online library that they used to mention the word "savings" positively in articles (mainly from the 70s and 80s), but in recent years most of the references have only been negative, eg:
Daniel and Miriam thought that by using their savings, they could stay in Panama for about eight months... When their savings ran out, however, the couple’s joy turned to sorrow. - "The Joy of Leading a Simple Life" w17 May p. 30 - The Watchtower (Study) 2017
There is an Awake article from 2011 "Why Save Rather Than Spend?" which mentions having a savings account and the usual ideas of spending less, keeping debt low and yes - growing your own food! It even mentions what it calls "legitimate debt", suggesting taking out a loan for a specific practical asset such as a house or car - unusual for the org, to my knowledge. But predictably, the article does not mention the options of overtime or seeking a promotion or higher paid job in order to save more.
