... then there's no reason to do it at all? I wonder how your grandchildren would feel about that attitude?

Just as no energy sector has ever flourished without government largess, there is also no completely clean form of energy. Coal mining is toxic. Oil production is toxic. Fracking is toxic. There's not an insurance company in the world that will write a liability policy for a nuclear plant - the government has to provide that insurance (i. e., YOU & ME! ... is that a business that you WANT to be in?) Are you advocating that we completely forget about a pretty good solution while we look for the perfect one?

So, who's "baking" your pie charts? Exxon/Mobil? The Heritage Foundation? ALEC? Koch Industries? Are you unaware that the Kochs are HEAVY subsidizers of PBS? - but that support is quite contingent upon content control.

I'd assert that if we stopped subsidizing fossil fuel, your metaphorical train would either be converted to run on renewable energy, or it would, indeed, just STOP!

My guess would be that you, personally, are heavily invested in fossil fuels, so your opinion about what's good for EVERYBODY is completely decided by what's best for your bottom line. Or ... perhaps you just don't give a tinker's damn about anyone else.
