My big weekend project is to install a shower curtain rod. There was nothing wrong with our old rod. It's served us well for the 13+ years we've lived in our home. But my wife, in her infinite-wifedom decided we needed a nice shower bar, one that curves outward. As Sgt. Bilko would say, "It has sweep."
So I went to a local hardware store--one run by Russian Jewish emigres--and bought a box of 30 3/16th-inch screws with 30 accompanying anchors. They cost $4.99--roughly 8 and 1/3-cents a piece.
When you make a commodity you can be outsourced. If you don't make anything special, anyone can do what you do.
So much of what is now done by ad agencies--"front-end" development, user experience protocols is infrastructure development. It's not differentiated. Or differentiateable.
As long as we make parity products ours will be a low wage, low margin, low value industry.
In other words, we'll be screwed.
