Who gives a shit? Standard of living for everyone is the greatest in the history of mankind.
How are you measuring Standard of Living? And, what country are you talking about?
If you go by the Human Development Index, then here is the "top 10"

Norway, Australia, Iceland, Canada, Ireland, Netherlands, Sweden, France, Switzerland, Japan?
If you are going by strictly by GDP Per capita, then the US moves up to #9, or if you go by GDP PPP per capita, to #6, #5, or #8 depending upon source....
But, these are all based upon "mean" values rather than "median" values ....
And, what you'll see is that the mean is significantly lower than the median, because, the truth of the matter is, that a very large portion of society is living on the edge, yes, they may have a TV or a car, but, in much of the country, no car = no job, and, you can pretty much get a TV for next to nothing... So, what you wind up with is a system where the necessities take up 90% of the person's income, and they spend 10% on luxuries, which are cheap in our society.
So, yes, in today's world, the poor have more "nice things" than the poor had 100 years ago, but, the fact of the matter is, almost 30% of the population in the country is "poor", and another 30% are running on a thin enough budget that something serious could bankrupt them.... So, you only really have maybe 40% or so of the country that could be called financially "secure" by any stretch of the imagination...
Piece of mind is worth a lot more than a TV or a fancy car.
