Our society has become much more "free flowing" and "creative thinking" is encouraged much more than "linear thinking". Being inspirational appears to be more valued than having substance these days.
In fact it's not uncommon for "linear thinkers" to work for "creative thinkers". With the advent of how we communicate with text, Skype, Facebook, Twitter, and Instagram we have become much more (casual) in our lifestyles and approach to life in general. Structure and formality have fallen by the wayside in many instances.
The "baby boomers" were big on "turning the world upside down" as a mission. Things today that may not seem so unusual were very radical at the time. ( Smoking pot, pre-marital sex/cohabitating without being married, protesting or not trusting the government, men growing hair as long as women along with getting their ears pierced, making statements like; "Never trust anyone over 30" and "I refuse to grow up!" were all part of being "anti-establishment", pushing the boundaries, and rebelling against structure.
In the past we were taught go to school, work hard, save your money, and build a good life for yourself. Today we have college drop outs becoming millionaires and billionaires at younger ages than ever before while many graduates are saddled with six figure student loans working in unfulfilling jobs. Divorce rates hover around 50%, having children out of wedlock isn't unusual, very few people work for (one) company for life, and solid investments rise and fall based upon rumors or things happening in distant places around the world. What was known to be true no longer applies.
Structure for many people gave them stability, predictability, and a sense of security if they'd simply follow the guidelines. They could almost put their lives on "auto pilot". Paradigm shifts seem to take place yearly if not monthly. Although an "anything can happen" way of life can be exciting the lack of structure also means there is so much "uncertainty". It also becomes harder to define "normal".
Ultimately our own lives can contain as much structure as we want. It's our views of everyone else's lifestyle choices who are different from our own that causes one to feel a major lack of structure. Everyone is "Doing (their own) thing". Another 1960s phrase.
