I've been working on this idea for some time on what exactly is Slacker Theory both economic and social. I've narrowed this into four focus points from my research and thoughts on this as a practitioner of the Slacker lifestyle.
Most People Insist on Working to Hard
Seriously any Slacker in history relied on the fact the vast majority of people work hard this could be slaves in Ancient times doing the work to free their masters and mistresses to do more important things, a laborer class that just wants to make money based on a work ethic and society expectations or a society that made allowances for Slackers (hippies and beatniks come to mind). The workers and go getters though pay taxes and are the backbone that supports Slackers who live off them one way or another I prefer getting tips for my Busking work and don't currently tap government benefits ,well, much. I exploit all the health care options I have many charity care and the free clinic while I support expanding Medicaid under the ACA the holy grail of Slacker health care options health coverage based only on income not trying to find a job or other silliness.
Modern Society is Good
This is important to modern society has safety nets and laws that help the poor. You get really sick in the US go to the ER. Your in some EU countries you get a neat safety net one can play. Modern families usually won't toss a child to the street and if they are disabled or has other issues its even better. And if someone is really in need most normal people will help the saps that work so hard. Of course Slackers do work in most cases enough to meet our low needs and wants, hopefully doing something we like doing just tend to be as few hours as possible for the best money ideally. But some don't and some work more doing things they like.
Its Not Illegal to Not Work or Not Work to Hard
This is the best part its not illegal to not work or work very modestly and apply for government benefits if needed, in fact Slackers find many other things more enjoyable than work. I am a gamer, I love reading books mostly non-fiction, I love watching movies and yes lounging around doing nothing or spending time with friends. And every hour I work more than I have to takes away from these more enjoyable recreational activities. When I was told to by a Social Worker to apply for jobs I did and set asked wages at $20 an hour what I felt was fair for mind-numbing stupid work full-time and the Social Worker class said to put down what was fair for the amount per hour. My High School shoved me a program when I was not properly motivated and planning for my future so had to go through his garbage when she found out she was angry but I wouldn't flip burgers having people order me around for less than $20 an hour. I went into Busking after High School finding I can make lots of money with modest hours at least enough for my needs and wants such as they are.
The Future will Take Care of Itself
Why worry about tomorrow? I pay my taxes for Social Security and Medicare but why save to much money and buy lots of things one hurricane in Florida you can lose all the stuff and money one has is better spent for fun now. And as an atheist (no afterlife to scare me) if things get bad one can always commit suicide I already decided if I get really sick to take that option doing so when one is "tired of life" is just as sensible. But as long as life is enjoyable and I don't have to work much then its fine by me to keep living. Other Slackers may have some savings or have some other things going on.
To end I will quote a line from the movies SLACKERS: My life may be crap (its not as I see it just the quote from a character) but I didn't work hard to get here.
Hate or love us Slackers have been around for thousands of years in one form or another, and this are my basic ideas on Slackers.
