Which are matters reserved to Government and not MPs. So you are back to a handful of well informed MPs.
A handful of informed MPs in government have executive portfolios in these areas. Which is not the same as having all power.
In any case, my argument is that this is a better system than having referenda on these issues because "the mass" have a pretty good track record of making dumb collective decisions.
As the implications of our departure from the EU are at present, a complete counter-factual, so are politicians.
Incorrect. These things can, to a certain extent be modelled. They don't know (in the strict sense), but they sure have a better idea than Dave the Bricklayer from Swansea.
all MPs have an immediate incentive and every available means to inform themselves with regards the economic issues.
As does anyone.
And do they actually take the time to inform themselves of the economic issues, properly, at the macro level?
Even the most silly backbencher can put up a reasonable showing in a Question Time.
Its amazing what intense briefing by the Civil Service or Party political advisors can accomplish. a showing on question time is just that, a showing. It's lines and arguments that have been prepared and polished and tested by many, many other people.
Yup. A lot of brain power has gone into those arguments and tag lines. Unlike in the brain farts often produced by the average member of the public.
They experience local issues and individual circumstances. From which you cannot draw any inference to the macro-economy.
the macro-economy is hardly the only issue. but even if it was, if it fails to relate to individual and local circumstances what is the point of it?
Parallel arguments can be made about every single issue. A voter will only be directly acquainted with his own individual circumstances. Then only valid evidence base for policy-making is macro statistics.
And there is a relationship between local and macro circumstances. What is not the case is that you can say anything about the macro from one data point of local, individual experience. But if you get the macro dynamics right, that will imply a positive effect on most people's individual circumstances. That is why, for the sake of everyone, you cannot make policy on the basis of the anecdotal personal experience and ill informed opinions of the average voter.
