Can confirm. I grew up in India and now live in the US. I regularly regress into a scarcity-oriented mindset (e.g. preventing all food wastage, avoiding spending on "nice-but-not-strictly-necessary" things, etc.).

Even though this mindset is incongruous and inefficient for my present circumstances -- and I'm aware of it -- overcoming childhood programming about it is difficult.

Old habits die hard, I guess.
