To be fair to public services, many of them can't or don't experience the same increase in productivity as seen in industry.
Your industry, and many others, like making electronics, toys, etc. experience economies-of-scale, automation, leading to large increases in productivity, and falling unit costs.
In contrast, nursing, education, medecine, police, etc., are very labour intensive, and don't see the same increases in productivity.
This is known as Baumol's cost disease.
It's why I can buy a chicken at 4 euro, cheaper than ever before, but the price of a haircut keeps rising. A barber can't cut any more heads compared to 50 years ago.
However, in saying all this, we could still do with much more EHR, automation, ICT in the public service, especially in the HSE.
