The problem is that any "crawler"/"lift" would be limited to maybe 300km/h speeds optimistically, and as result take a month to reach GEO.

Let's see...a month at 300km/hr takes you 216000 km. Do you really think GEO is almost as far away as the moon? Or are you just arithmetically challenged?

Hint: at 300 km/hr, GEO is about five days away....

Does the phrase "Great Depression" mean anything to you? That one took WW2 to work its way out of the economy.

As to "food prices are way up", there are about as many indications that "real" (adjusted for inflation) food prices are down as up. Just depends on what you're buying...

To the point where in the most prosperous parts of the planet (US, the EU, China (for different reasons, but the prosperity part is coming along there)), population growth rates are negative absent immigration.

If the entire world were raised to EU standards of living, population would decline to rather lower than current populations, and stay there forever....
