According to the US Bureau of Economic Activity, the real US economy (i.e. non-public sector) spends just over $1 Trillion / year on non-structural fixed assets.
This number excludes the cost of buildings, warehouses and factories but includes all household, farm, business, and non-profit organization spending on fixed assets. A precise definition is found here.
Roughly half of that amount ($537 Billion in 2011) is on information processing equipment and slightly over half of that amount ($279 B) is software.
Spending on transportation equipment (trucks, cars, ships) was $232 B and industrial equipment (engines, lathes, robots, …) $178 B. Furniture and other types of equipment (e.g. agricultural, mining, oil rigs, …) was $194 B.
Within the $537 B on information processing equipment, is spending on computers ($79 B ) and network equipment ($77 B). The 3rd largest sub-category after software is medical equipment at $72 B.
So the largest single spending area for fixed assets is for software which is a virtual asset! Henry Ford must be spinning in his grave!
“What a pitiable thing it is that our civilization can do no better for us than to make us slaves to indoor life, so that we have to go and take artificial exercise in order to preserve our health.” — George Wharton James, journalist, author, and speaker (1858-1923)
