To be fair, I believe that motivation comes from the reader, not the author.

Again to be fair I believe you're projecting: you may want to be a millionaire for the lifestyle it affords, whatever that means to you. The book is a recipe on ways to retain wealth and anecdotes on how people accumulated their own. It's not a self-help guide to motivate people to become millionaires. I think it's assumed if they're reading they book they're already motivated and need to know how, not why.
The value would be discussing why you want to spend it, why you should reconsider because it wouldn't affect happiness, something like that.
Some do. Others do not.
My boss makes ~300k a year base. He drives a ten year old Golf, carries zero debt, and plans his (very infrequent) meals out around "which restaurant is running a 'kids eat free' special today?"
His goal is to build up a sizeable savings, retire and live off interest, and provide generational wealth for each of his children.
One of his peers makes ~300k a year base and enjoys driving a Ferrari that costs more than my house. Different strokes for different folks :)
Currently it basically tells you that if you spend the least possible, you accumulate wealth faster. Well, wasn't that obvious.
One reason is that if one accumulates that wealth, and puts that wealth to work itself making money (i.e., investing it) then one obtains an income stream that is separate and apart from the number of hours per day one can spend "working".
Accumulate enough money that is itself making money, and one can live comfortably without having to spend 40+hrs/week "working" for one's income.
I don't plan on retiring, but i'd feel so, so good if i hit $X tomorrow.
The economy could still go down, but as long as society doesn't collapse retirement-amounts can bring massive QOL, even if you don't live like you're rich.
People want to be millionaires, not to stare at 7 digits on a webpage, but for the lifestyle it affords. This book just assumes the end goal is the number on a bank account.
