Gradual improvements on core capabilities are what's needed.

Consider the Michoud Assembly Facility run by Marshall Space Flight
Center

In the 1950s and 60s they worked on Saturnshttp://mix.msfc.nasa.gov/IMAGES/HIGH/6870792.jpg

In the 1970s they switched to External Tankshttp://mm04.nasaimages.org/MediaManager/srvr?mediafile=/Size4/nasaNAS...

These External Tanks using a design I cam up with become a building
block for a very large launcher as I describe here;

http://www.scribd.com/doc/30943696/ETDHLRLV

To support the development of solar power satellites that beam
infrared laser energy to 8,000 ground stations at the same time -
making enough money to support continued operation of the system by
generating a total of 10,000 MW and earning $4.38 billion per year per
satellite.

http://www.scribd.com/doc/35439593/S...-Satellite-GEO

This power satellite can operate at GEO to produce *10,000 MW as
mentioned.

More advanced systems can be orbited nearer the Sun to produce 220,000
MW - upping revenue to $30 billion per year per satellite even while
reducing costs from $0.05 per kWh to $0.015 per kWh.

A 220,000 MW laser beam energizing a laser propelled rocket that
produces an exhaust speed of 22.44 km/sec produces 1,000 metric tons
force (the same produced in the ET derived rocket) - but reduces the
propellant fraction required to get to orbit (9.2 km/sec) to 0.337 or
263 metric tons of hydrogen alone. *Allowing the 50 metric ton empty
vehicle carry 467 metric tons to orbit as a single stage vehicle!!

The same vehicle - when powered by laser rockets with 22.44 km/sec
exhaust speed can carry 315 metric tons to the moon and back or even
Mars and back using 415 metric tons of hydrogen in the same 50 metric
ton vehicle. *This is the capability of laser rocket.

But we need to do things well regardless of the technology core.

Your conventional LH2/LOx stuff is good enough as is, along with
powerful ion thrusters should more than do the trick, but not if
you're never in charge of anything that matters.

Since you refuse to blame anyone except yourself, and insist that the
past isn't ever supposed to affect or influence the present or future,
then why don't you fix whatever's wrong with yourself, and then show
the rest of us exactly how it's all done faster, better and cheaper.
Try to remember that I'm one of the few that's actually on your side.

Go to your rich and powerful friends and get their unlimited financial
support, and start doing exactly as you say. According to your own
advise, in no time at all you'll become another trillionaire that pays
little if any income or business tax, just like most of your best
friends that are already trillionaires or at least multi-billionaires
keeping most of their loot and other forms of hoarded wealth offshore
or in some other perfectly legal tax-avoidance investments that remain
untouchable to anyone except yourself.
