Only because they have not got wealth and think that is what wealthy people would wear and drive.
This is also true, it's mostly living the assumption of what they believe a wealthy person would do. On the contrary, some wealthy contented wouldn't.
Over here, people would rather have you believe they're rich, because they feel ashamed to be seen as "struggling"
I haven't seen how foreign Indians live, their financial and all. However it's just saddening how some people view wealth as the things they need to wear, eat or even drive and prefer to be in debt.
