And we look to models of - what did you say- "comprehensive and sustainable solution", where? There are- to some argument in your stumping for "our" ( like "we") "paying fair share"- some reasonable ideas regarding corporate tax.  There is little counter, I believe, to sum that "maximum benefit" of resources has, and remains, seriously amiss as to intent.  The great error of this age with regard to finding equitable and just distribution of wealth- if it is presumed to be of established aspiration- is in the assumption that certain forms of taxation are justified in their ends in defiance of the most axiomatic, categorical, precepts of greater justice.  The flaw of divining  "consent" from forced allocation of resources, that force substantially based upon arbitrary presumption,  constitutes a paramount violation of first principle.  Try as you may, it cannot be altered to favor, and the results in consequence to society are manifest.  "Funding" is not THE solution. Think systemic!
