Um, hi, it won't. We aren't going to get to the space economy. The planet is literally dying. Vertebrate and insect populations are both in complete freefall, and global warming is going completely unchecked. Most estimates are looking at 50-100 years before we start seeing mass famine and water shortages leading to die-offs of humans in the billions.

A "space economy" is a hilarious pipedream in our current situation.
