> massively increased everyone wages due to increased efficiency
a computer won't increase the wage of someone whose work is unrelated to the procurement of the computer/system (even if their work was made more efficient).
For example, a checkout clerk now dont need to compute, because of the efficient Point-of-Sale system (when previously they'd need to recall prices). So even if the output of the clerk is now higher, they could be less skilled and so the supply increases, leading to lower wages.
The people whose job is to procure the computer systems _do_ get increased wages. That's why so many software engineers are rich.
