Cost-wise it's efficient because almost all human labor has been removed from the equation (except for select crops where hand-picking is still needed).

Good point Ralfy. I think the wider point here is that the pattern has been to make people/workers redundant. Cutting costs probably being the overriding motive. Just another sign of limits to growth.

Ways technology have changing plumbing:
40 years ago - PVC and ABS plastic drain piping changed the materials cost and skill formerly required to connect cast iron bell-spigot drain pipe. Labor cut to 1/3 the time per lineal foot.
40 years ago ditto PVC water pipe - changing from threaded galvanized or soldered copper. Materials costs down, skill level lower, man-hrs/lineal foot way lower.
35 years ago - no-hub cast iron piping systems evolve. Where plastic could not be used and cast iron was required by code, no-hub eliminated the complicated traditional way of joining cast iron, with melted lead and oakum packing. Just tighten two nuts on the connector's stainless steel pipe bands (larger versions of the pipe clamps used on radiator hose or poly pipe with barbed fittings.)
20 years ago - PEX pipe makes more in-roads into water pipe materials/labor costs. Snake it like Romex cable. Fewer fittings. No solvent joints - just machine-made-up press-fit joints. Labor per lineal foot continues to drop, and skill level drops another notch. The "skill" is in the joint-making equipment.
10 years ago - Then Shark Bite came out and even simplified PEX joining more. Just push to fit. Simple tools. No major tool-up cost. Now even fewer plumbers, with lower skills and cheaper tools, are required to plumb a building. And DYI plumbing becomes even easier - fewer calls to the "pros".
20 years ago - in-pipe camera and pipe tracing systems come out - no more digging up pipe to find out where the plug is and guessing where to dig. One guy can find the plug or failure, locate the pipe, and dig it up in a fraction of time of the old way.
20 years ago - directional horizontal drilling. Not the type for drilling for oil in shale. This is the type that can drill under roadways to make a 6" hole to pull a 4" water main through it without tearing up the road. Takes two guys 4 hours to put in 100 feet of buried pipe. No other trades involved. No major excavations. No road patching. No shutting down the road - no flaggers, no pavement cutting, trenching, major excavations and big backhoes. A bobcat can handle the initial digging to set up either side. You see it everywhere now. Gas mains. Data cables. Water lines.
There are a dozen other examples I could cite. The bottom line - man-hours per lineal foot of pipe have plummeted over my career, thanks to materials and technology advances. And the skill level required to do the work also has plummeted.
There is no safe-haven for labor-intensive jobs, regardless of arena. As long as man has an engineering bone left is his/her collective body, there will always a better mouse-trap in the works, ready to put yet another mouser out of work.

We're already in the age of self-flushing toilets!
