I'm disappointed and feel slightly bait and switched. Her husband's income enables her take on ephemeral gigs and run a blog full-time instead of working at a regular 9-5 job. Also, her extreme frugality is just a fun thought experiment, blog topic and hobby for her. It is impractical and an ineffective use of time for non-hobbyists --- if she had to work a full-time job, she would be better off spending more time developing her career and less time being extremely frugal.
Additionally, I like reading about 1st/2nd generation immigrant stories but she appears to also solve the integration and cultural challenges of her immigrant background by marrying an all-american rich white guy.
What if it's an important part of the equation? Stable marriages have rather strong inverse correlations to poverty levels. Maybe finding someone rich in this case was especially fortunate, but even marrying someone of similar economic means tends to be a boon (on average at least).
And pathology... most people are "pathological" in some way. It's hard for me to tut about personal inclinations too much.
Marrying a rich man was the deus ex machina.
I thought the talk about breaking the "cycle of poverty" was pointing towards a heroic use of frugality to overcome, but no, solution was marriage.
And then the extremely/uncomfortable frugality, as opposed to healthy frugality, after becoming rich points to pathology more than anything else.
