The problem is Americans always have to be fronting, they have to build that big totem pole. Cause you gotta make people think your some high roller and impress those "Friends"
Most likely this is what the typical American will do who earns 100K
#1 Permalease a 500-800 a month BMW/MB etc.. forever (not just one but two or more ie his/hers and the kids), and don't forget the cost of insurance.
#2 Buy a huge zero lot McMansion box house
#3 Everyone has a 100 a month phone plan, (his/her/kids) 300-400 a month or more, annual upgrades of those iphones as well.
#4 Super cable package and super internet package (300 or more a month)
#5 if they have a small child, send them to l33t kindergarden for 20-40K a a year
#6 Murican wife usually does not cook, so spend tons of money a month on frozen food
#7 Murican wife cant cook but they buy the 2000 dollar l33t cookware to hang over the big kitchen, over the fancy unused Wolf or Garland stove/oven.
#8 if they have kids, they gotta wear those 90 dollar made in china name brand outfits.
#9 Weekend outings every weekend to entertain "Friends"
#10 yearly tv upgrades, hey that new 4K TV is out, lets get rid of that crappy 1080P. now I can show my friends our new badass 4K tv.
#12 if they have kids send them to all kinds of programs but the l33t versions, ie soccer,karate,piano,ballet,etc.. but 5-6 programs at the same time.
#13 etc.. usually the end result is spending more than what comes in, typically 40-100K credit card debts or more.
