Would they?
For people to know better, they first have to be able to process
the information given to them in a useful manner. Without having
been taught and trained to analyse labels for content and
meaning, simply reading them is pointless. When the label reads
"Pork sausages, 100% meat", most people do not realise that a,)
this does not mean that these bangers are made from 100% pork; or
b,) that the legal definition of "meat" is very different from
the shopper's definition and includes a legally permitted
proportion of connective tissue and mechanically recovered meat
slurry. When a clothing manufacturer patriotically waves the
flag ("100% American owned") and the laundry tag sports the very
legible words "Designed in the USA", how many customers will be
aware that this does not mean that this item of apparel or any of
its constituent materials came anywhere near the US before it hit
the shops?
The same applies to politics. "Fairness" is a very common
buzzword -- but it can be defined in oh so many ways, and a
candidate's election machinery will very carefully avoid letting
itself get nailed down on which exact definition it goes with at
any one time and in any given context. Ditto "poverty" and its
opposite, "rich people" or "the wealthy": good luck finding out
which yardstick is being applied and whether it actually makes
sense or is simply an arbitrary measure defined by the campaign
manager on the back of a paper napkin for the purposes of this
one election. Facts and figures: do they make sense, and how can
you possibly work that out without having some knowledge of
economics or statistics at a level definitely not taught at
school?
Possibly most importantly, your statement that "an informed
electorate is a simple solution" fails to take into account the
vast gaps in the electorate itself when it comes to processing
information. Wide parts of the electorate are functionally
information-illiterate, and those who do have the requisite tools
to parse, analyse and interpret the government or campaigning
bumf are very much in the minority. So to have an informed
electorate, we'd first have to have an educated electorate, a
populace with a high level of high-quality education -- and that
is anything but easy, I'm afraid.
