To the people talking about 'isn't it funny that when people make 60, they spend 60'?:
When I studied econ in College we reviewed lit that covered the so called inability of people on the upward side of mobility to scale back their spending and convert new money into savings where previously none existed. Most of the time people saying this are leaving out extremely important details or are fibbing. Examples I recall that fuck this up for most people:
Many westerners fuck up their taxes to a degree or have other miscellaneous nonsense pop up from their less than stellar income's past which produce a slow drain. Similar challenges occur with those heavily in debt with student loans. I read one horror story where the DC for her student loan had to wait in line as the gov was already levying her checks. Another with a similar situation regarding medical bills or various other debts. To wit: a scale in income, even significant, normally means little these days depending on where you live and what your situation is and the further up you go the nastier it can be - until a breakpoint of like 55k (that was years ago so i suppose true economic peace might come for most at around the 75k mark). Some debts only become relevant once you are able to pay them (obviously) and those payments are almost never fair. Many people who said they had savings technically do - and have many bills they haven't actually paid.
The people who do manage to live super frugally actually end up not saving as much as they think they are or live altogether unhealthy lifestyles as a result.
Many people straight lie about their income security.
The system is such that many people believed their investments were any better than the next guy's debt when, truth be told there are many risks in certain portfolios and very little insurance to back it up.
The list goes on and on; some of it was horse shit, some of it legit.
There are many reasons why going from 20 to 40 to x isn't as uplifting as it once was.
