Housing is notably not included here. Further, while it says government or non-profit provided health care and educated are included in the incomes for countries where it's available, the countries where it is NOT available don't show a reduced disposable income to pay for these things. These data do not show what you think they show. They already show a smaller gap than you had originally implied, and as I stated earlier, that gap is going to narrow substantially when the rest of these factors are taken into account.
