How to create jobs if they don't do this?
It used to be that flooring, structures, pavements could last for
10, 20 years before they did any renovation work on it.
Now, every 1 to 2 years, for the sake of job creation and the fact
that MPs have promised some kind of 'upgrading' works to show that
they are doing something for the constituents, you will have all
these drilling, relayering or digging of holes only to fill them up
again occassionally.
Plus election is coming so you can use the upgrading as an excuse
to get more votes.
