There are many people in my highly liberal and progressive PNW town that drive trucks. The majority seem to be decent people based on my interactions on the road with them as a pedestrian and cyclist.

I do agree most people don’t need trucks, and it’s more of a performative masculinity thing, or maybe that’s just what they’ve been conditioned to like.

I use a spreadsheet and write down everything I buy and manually categorize into about 8 categories. Simple and effective for keeping me on track w.r.t. my financial goals.
