Absolute horse shit <| sep |> It is enforced constantly . I work at a local chain that sells alcohol , and we get an average of 30 fake IDs that we catch and take from people a week . Our store survives because of the amount of alcohol we sell . # 3 in the nation for Fireball sales <| sep |> What aminok said . 3 D printing is important . Not only are there additive printers but small biochemical reactors as well . People will be able to manufacture their own medicines . Home power generation will allow for home water treatment sewage , mesh networks will allow for hardwireless internet networks . Etc . it ' s the 21 st century not 1955 . The paradigm of giant infrastructures , huge single widget factories , continental spanning supply chains is fading . So , employment will look differently as well . People will be able to produce many products themselves that once required a lot of specialized labor spread geographically . So why work for Joe the factory owner ? I see people creating smaller local versions of these current giant manufacturing methodologies . IMO , we ' ll see wealthy neovillages , instead of a baker , candle maker , etc . we ' ll see home sewage treatment biobalancing specialists , bespoke knife makers , pharmaceutical designers , etc . It ' s farking exciting ! Don ' t see a reason for all of this doom and gloom .
