Is there a reason light travels so fast?

My only guess is that it is a result of having no mass, or close to no mass, but the extreme acceleration puzzles me, photons move at 299,792,458 metres per second without incredible amounts of energy accelerating them..why?

Snarky answer: why does everything else move so slow?  

Seriously though, that's the real question.  If we decided to rename *c* from 2.99\*10^8 m/s to 1.00 (*i.e.*, switching to units of light-second per second), then why does everything else travel so much slower than 1?  

The answer seems to be tied up in the fact that everything else has inertial mass, which seems to require great amounts of energy to accelerate.  But that raises the question: whence the mass?  Our best guess, the Higgs boson, has proven elusive in laboratory experiments, so we're all left scratching our heads...  

Less snarky answer: good question!
