For thousands of years, mankind struggled for survival. We invented agriculture, shelter, clawed our way into modern medicine and eventuallt multiplied on the face of the earth.
But as it turns out, the limit of our growth was that precious currency of desk space. We scoured the ends of the earth and wept, for there was no more desk space left.
While I kinda agree with this, I've known some folks whose standard for 'ready' was a lot higher than previous generations/other cultures.
For example, I could get a folding desk, move my home office into my bedroom, and put 3 kids in bunk beds in one room.
Or I could say I'm not ready to have kids as I only have a 2 bedroom home, whereas in a few years time I'll be able to afford a bigger place.
