I, too, am building up financial resources for the point where I have to take care of my parents. They did not plan for their financial future, and now that they have split up, they are in an even more precarious situation.
Although my mother was an excellent saver (to a fault?), she was not interested in learning how to amass/raise capital, nor in any type of investing, other than older, traditional CDs, etc. that are not financially viable in this age of debt and funny money in the US.
My father is a spendthrift, so there is always a hole in his pocket.
I see in them the reluctance (or refusal?) to shift from the "American Dream" (go to school, get a good job, save for retirement, your employer/the government will take care of you) to what it more realistically takes to grow any sort of wealth in the current US financial climate.
Consumption was the biggest negative factor, I think, as well as the inability to sacrifice some of the present for the future. It seemed necessary as a kid growing up, if we were going to keep up with the Jones'. I remember being envious of having an "Ocean Pacific" jacket as a kid, and the only pair of "Britannia" jeans I had came from a second hand store. I was very caught up in the whole name-brand thing... That was the 80's, for me.
Now I save up and invest in Real Estate, effectively short the US dollar, as that seems to be the vehicle I am most comfortable with. My wife and I are accelerating the process as much as possible, without scrimping too much, as her mother, likewise, has little to live on. And being at the mercy of governmental healthcare is the pits, as I watch both sets of our parents attempting to navigate those hoops.
So I understand the author's motivation from my own point of view, and I think she has adopted practices that will serve her well, as long as she also has enough consideration for taking care of herself, her husband, and any kids they may choose to have, as well as her parents.
It is definitely possible, although I find I have to ignore all of the "consume this now" messaging I perceive blasting at me from all angles in media.
Side benefit: Ignoring that media helps on the political front, though, as well. I used to become (still sometimes become?) the raving lunatic when I pay attention to what higher politicians (non-local) and larger government employees get up to, technically on my behalf.
I feel much more calm ignoring that and focusing only on what I have a chance of affecting: My home, family, friends, and immediate neighborhood. I have even served in local government, and although I did not enjoy it (the waste! the pettiness!) it helped me make more social contacts locally that have positively affected my life and immediate living environment.
I now volunteer more often, as well, as there is much need in the community, and few obvious answers (to others' points of view).
It seems to be working for me... YMMV.
