In the future

The future meaning mid-21st century...

• People will smell more.  Hot water will be much more of a luxury
• Meat, especially beef, will be too expensive for most citizens
• Fresh, safe drinking water will be difficult to come by in many locations
• Septic tanks and outhouses will make a big return.  People who can install and maintain them should have little trouble finding work
• Local "low tech" security services: sheriffs who live in town and part-time deputies.  
• Horses.  They'll be back as common transportation, especially in more rural areas.
• Golf carts.  Huh?  As a means of cheap local transport, their price will be hard to beat, at least in places where there's enough electricity to power them.
• Firewood makes a big comeback... in regions that can learn to treat it as a renewable resource
• Gardens, gardens, gardens: everywhere there's decent soil and rainfall and somewhat reliable climate.  Look for small scale seed firms to pop up.  
• In urban areas where electricity supply is sketchy, look for ice boxes to come back... Assuming people can figure out how to build and maintain ice houses.
• Radio makes a comeback: Far less power than TV.
