Seems to me that we should be asking the question why is the speed of light so slow!
We're forever discussing the Higgs and how matter gets (some of) its mass but we spend precious little time discussing this relationship:
c0 = 1/(μ0 ε0)^0.5
That is why vacuum permittivity and vacuum permeability 'conspire' to slow down light to its known value.
