There is no outrage, save by the professional agitators for more unregulated monopolies
How is that de-regulated trucking industry doing? High turnover, low pay, multiple occupational diseases? you don't say.

What you get from privatization is higher costs for all but the most profitable segment of the business, monopolism and eventual fraud, deceit and theft.

As for that claim, I refer you to a Grade School web site...so you will stop embarrassing yourself.

I compare exhaust velocity (temperature or equivalent) with final velocity, see Tsiolkovski equation

for a GRADE SCHOOL EDUCATION you clearly need.
See that "exhaust velocity" figure? Exhaust velocity IS (linearly related to)temperature!

and reality, hope wins the money run every time
There will never be a nuclear thermal engine with an exhaust velocity higher than the melting point of the nozzle materials used (circa 3800 F) and thus, not one single iota of longer range flight for a given rocket size.
What's available for non-electrical accelerators is thermal velocity exhaust which most of us know means a maximum final Delta V from source of circa 58,000 ft/sec and that won't even get us to Jupiter in a lifetime (baring gravitational slingshots, an entirely different issue)
And electrical conversion of thermal energies are losers, with a minimum of 50% of the energy lost as radiant heat (Thanks Carnow).
So, nothing good here. Unless you can fission and confine the daughter products without mechanical contact (think gas fission at plasma temperatures) you will not go any faster than a chemical rocket would move you over a trans-martian orbit.

Bluntly, the more statist the nation becomes, the more intelligence the nation displays. China before Mao? Stateless and ignorant. Now? Running the world
The Soviet Union? Before Lenin and Trotsky, feudal, ignorant and helpless. During Stalin, absolute victory over the Hitlerian war-state.
In the end, only the organized nation-state can move out of the stone age.

Yes, it is worse off, as the slaughter of 1 million innocent Iraqis to "protect our allies such as Israel...and our control over a significant portion of the world's oil" demonstrates.
When the leaders of the 'free world' can say that out loud (Dickhead Cheney in PNAC open letter to Bill Clinton, dated 1996) and then DO that mass murder and NO ONE brings them to justice, the world IS worse off.

Actually, Capitalism is only unparalleled in extracting worth from labor. One has only to look at the working conditions of the Chinese 'volunteer labor' in those factories/barracks where hundreds of thousands live at the beck and call of Capital to realize the individual had far more personal gain as a farmer under communism than he or she has in a guard tower ringed, machine gun toting gestapo riddled 'workplace' under Capitalism.
Ultimately, the effects of Capitalism are mass deaths, the extinction of species, and the displacement of workers into destitution.
