That’s “piker”, IIRC.
Anyway, there was a Volkswagen ad showing a Beetle with the caption, “live below your means”. My first car was a 1956 Beetle.
Dad gave me a copy of “The Richest Man in Babylon” whose advice was “a portion of all you earn is yours to keep”. So I practiced thrift all my working life. Never felt deprived and never envied anyone unless they could play the piano better than me; if I bought a new car I drove it fifteen years at least. My 2002 minivan has 246,000 miles & runs like a champ.
Wife & I are retired and could live off either pension or investments; we feel blessed.
Having a sense of thrift and avoiding excessive consumption is the way to go. Many reject that, however. Tough for them.
