"I think progressive taxation will have a role to play..."

Nationally and locally we have "progressive taxation".  Why then do we have an issue?  Please some specifics, some concrete figures not vague homilies.

As for the "homeless" and my "caring", If Camus is too deep for you perhaps Matthew 26:11 is more comprehensible:  "For ye have the poor always with you; but me ye have not always."
