Gonna quote the study again:

"It is important to understand that the DLS represents a minimum floor for decent living. It does not represent a an aspirational standard and certainly does not represent a ceiling. However, it is also a level of welfare not currently achieved by the vast majority of people. A new paper by Hoffman et al finds that 96.5 percent of people in low- and middle-income countries are deprived of at least one DLS dimension."

Firstly- Are you so selfish that you refuse to change anything about your lifestyle in order to provide people with an absolute minimum standard of life - a standard that you have identified as abhorently poor by your standards?

Secondly- Change on your part may not even be required. Tax on production (i.e. corporations) would cover the majority of it, and the rerouting of production from useless things like casinos and yachts would cover the rest.

Finally- additional taxes and such would not even be required for many changes, just spending more efficiently. As an example- Very rural places all over the world have train and bus service. It's a matter of choice that the US doesn't, not a matter of practicality. We spend all of our money on highways instead, which are far more expensive per person per mile. Investing in rail, like Europe and China have done, provides far more use for far more people.
