There are people who just don't respect other people's property or they are jealous. I met a guy who came out to find his meticulous Ferrari 512 Boxer, had been keyed while he went into a shop. Also, when in grade school, some classmate bragging that he had keys a new Porsche 930, just to f*ck with the owner. Or simply, when I used to drive a Porsche to work (we share a parking lot with the local school department) and I would find new door dings in my car every few days)...also had a brick thrown threw the side window once. People just don't respect other's people's property.
This is especially true in my neck of the woods.
I live in the Province of Québec, and unlike the rest of Canada, we, as a people in general, seem to be very left-wing oriented/socialism-prone (I don't include myself in that assessment, the majority of the time - then again, I usually am not in line with my people's way of thinking - go figure), and over time, with the help of our nation's past history, we somewhat have become very anti-wealth, so to speak.
When I read the papers or watch the news and read the opinion columns, it seems we are very wary of people making their way to the top, especially those in the private sector - bankers, CEO's, etc.
I don't know if it's out of jealousy, or hatred, or simply because of fear of questionable income, but a lot of my coworkers, and people I interact with on a daily basis, despise big cars, very big houses, people with secondary homes, and the likes. It's like if a person has some kind of wealth, then he or she must be a crook or earned it through less than stellar ways (crime, collusion, corruption, etc.) or should be ashamed not to share it with everyone else.
Hence the reason if I had a nicer car, I'd be wary parking it in some spaces - it may get some unwanted exposure from some jealous folks.
(PS.: my opinion isn't science-backed, only an observation that has been well-fed over time).
Neither do I. Or I talk about it, but I stop when people start talking prices.
