I think the most achievable method to get this standard of living to everyone in short term is to properly define the limit as it applies to everyone. Giving everyone a guaranteed $140k, $35k per adult and child, would be exhorbitant in many places, though slightly more understandable if you’re limiting to the USA alone, and still not cover the highest cost areas at all. Giving the majority of people $20k per person and child, is doable and could more easily gain public support, and is sufficient.

Muddying the definitions and pushing an ever higher number like this author is doing doesn’t seem beneficial for the goal of getting people out of poverty.
