Add to this another issue which I see so rarely brought up. If we get past breakeven to the point of practical power generation, we still have a nuclear waste problem since all breakeven computations I've ever seen were for deuterium triitium reaction which will produces fast neutron which will eventually make the reactor core and some amount of material nearby radioactive waste. At just what level and how much per amount of energy produced I don't know I assume because no one has bothered to project an unknown design into that much practicality of concern. I believe the deuterium-deuterium reaction is quite a bit more difficult and I don't see the issue being addressed that way.
I'm ok with public money for research - heck, I'm ok with some money used on thorium reactors too, but I don't have my hopes up and whatever money goes into that bucket needs to be smaller than more immediate renewable energy research into improving solar (either by making solar thermal tower designs better, or improving PV panel life and cost, or improving battery storage). That and a whole lot more money towards efficiency gains too. And it would sure be nice to have politicians talk about a sustainable population target and changing the economy/tax code to get off this pro-natal kick.
