Some of my friends know my salary, but I've never told anyone except my family and my SO whats in my Vanguard fund, my capital one 360 account, or my regular bank checking account. I've mentioned purchasing index funds among friends a couple times but so far its peaked the interest of nobody except one other friend who opened his Vanguard account sometime back in 2009 or 2010. The status quo among many in my age group seems to be constantly purchasing high end liquor, eating out, high priced electronic/mechanical toys, car modification, and just about any other activity you can endlessly dump money into. I rarely participate in this anymore, though I used to be very fond of mid-priced bourbons and lost many a thousand dollars of investment returns on this liquid temptation.
I'm not living in a fancy place, though my vehicle is almost new at 6 years old/100k miles, and my lust for electronic equipment has been satisfied a few years ago with the assembly of my entertainment system/PC. I wasn't living frugally back when I put this all together but I had enough common sense to realize that if I minimize my rent expenses as much as possible and move closer to work I'll save money every day.
I think my living conditions would best be described as modest with a few carefully selected luxuries. At this point I may be saving around 25-30% of my net income per year. After my SO begins her new job next month that should edge up slightly as she begins to pay for some of the rent/electric/etc.
The folks at the local Chinese and Italian restaurants that I used to wastefully order from must think I'm poor now. The Italian place is really screwed, I got a pizza stone and now I realize just how much they mark up those pizzas over the cost of ingredients :)
