Only math PhD's, please.?

So, I hold no higher math degrees.  I took a little higher math and I learned about jet engines and what not in the military but beyond that high school math is pretty much it.

In my very limited mathematical capability, I arrived at a rather disturbing conclusion and I'm hoping one of you people that actually know a little bit about math can make me look like a moron.

Basically I looked at inflationary rates, GDP growth and expansion globally, and how costs in the Aerospace sector typically even outpace the cost of inflation, and arrived at the following...

That so long has Humanity uses money, what we have as far as dreams of exploring space colonizing the moon colonizing Mars Etc, are just that...dreams.

I arrived at the mathematical conclusion that because we are bound to a system of currency we will never ever ever leave this world and that we are in fact slaves to it for eternity.  That under the current system things aren't getting any cheaper and never will get any cheaper, to the point any future space travel from a budgetary standpoint is ridiculously laughably impossible.

Now I know there are a lot of people out there smarter at math than me.  I'm hoping there are a few PhD mathematicians with economic backgrounds that can say, oh no I've actually graphed it out and with the current economic system we should be able to afford a mission to Proxima Centauri by the year 2200.

I am fairly certain that so long as we use money we are stuck here FOREVER.
