The comment you quoted was from a post about what can happen if the system is made more productive.
I don't think anyone disagrees with what can happen if any system is made more productive.
My point was that in making the system more productive and efficient does not always and necessarily transfer into cost savings. In the private sector it may just mean increased revenues, in the public sector it could just be better delivery of services.
It is of course possible that new processes, training, technology etc can result in cost savings in the round but in general terms they typically require investment (more spending) before the fruits of those efficiencies are borne.
In the end, decisions have to be made as to what measures are taken to spend public money.
As can be seen above, and from this topics sister thread about specific cuts and savings, there is a variance of opinion on what measures should be taken.
My point is that nobody disagrees with the Fiscal Advisory Council because fundamentally what they are saying makes sense.
But the FAC has no remit, and is therefore effectively redundant on what specific measures should be taken in order to adhere to its advice.
Eg - The FAC advises
"For 2019, the Government should stick to its existing plans as contained in SPU 2019. This means that no additional within-year increases should be introduced without offsetting measures."
Yesterday however, the government announced a €10m package for the Defense forces. I saw no mention of offsetting this cost. The government is not adhering to the FAC advice.
Does the FAC have advice on how or where this cost should be offset? No it doesn't.
So should Defence forces have to make do with incomes that place its members on FIS? Or should their incomes be increased with this €10m package? If so, where should the offset occur?
I'm not asking you to answer these questions, just emphasizing the inadequacies of the FAC relative to the political issues facing the (every) government.
In turn, to me, the FAC is a waste of resources because it offers nothing that is not already inherently understood. That it is not inherently adhered to is a consequence of political considerations far beyond its remit.
