Particle physicists want money for bigger collider

What the Europeans will do is harder to predict, because
a lot depends on who has influential friends in which ministry.
But I think particle physicists have dug their own grave by giving
the public the impression that the LHC would answer some
big question, and then not being able to deliver.

Particle physics may have reached the end of the line
===
CERN’s press release of plans for a larger particle collider,
which I wrote about last week, made international headlines.
Unfortunately, most articles about the topic just repeat the
press-release, and do not explain how much the situation
in particle physics has changed with the LHC data.

Since the late 1960s, when physicists hit on the “particle zoo”
at nuclear energies, they always had a good reason to build
a larger collider. That’s because their theories of elementary
matter were incomplete.
But now, with the Higgs-boson found in 2012, their theory –
the “standard model of particle physics” – is complete.
It’s done. There’s nothing missing. All Pokemon caught.
. . . .

Particle physicists had a good case to build the LHC with
the prediction of the Higgs-boson. But with the Higgs found,
the next larger collider has no good motivation.
The year is 2019, not 1999.

There are more practical uses for science funding than building a larger collider. Particle physics has had an inordinately large piece of the funding pie because of the enormous success of particle physics for building the bomb. We don’t need to know how to build a bigger bomb.

False Claims In Particle Physics
By Tommaso Dorigo | January 20th 2019
===
'' . . . what does the idea of a "God particle" have to do with the Higgs boson?
Very, very little.
The Higgs boson is in fact the result of an almost magical mechanism,
called in its non-trivialized version "electroweak symmetry breaking" (EWSB).
. . .
The universe "chooses" one among an infinity of possible
minimum-energy states to be its vacuum, . . . ''
https://www.science20.com/tommaso_dorig ... ics-236226
=============

"God particle" was the result of an  "electroweak symmetry breaking"
(EWSB).  in an infinity minimum-energy states . . . of vacuum.
===
a) If the Higgs boson ''completed the standard model'',
then why do ''Particle physicists want money for bigger collider'' ?

b) If '' the standard model' isn't completed, then . . . .

c) CERN / LHC principles are - 
1)  the higher energy and
2) the deeper vacuum
the stronger the  "electroweak symmetry'' can be broken and
  more new particles can be discovered.
But where is the border of this CERN's idea?
Is it LHC around our Earth ?
Or, maybe, the border of CERN's project is LHC between Earth and Moon ?
Nobody asks of the CERN's border.
