The number of different taxes is constantly increasing, obfuscating the total tax burden, and making democratic accountability almost impossible. Additionally, tax collections are already at a historical high, while government deficits world-wide are also at record levels, with services on the decline, and no realistic prospect of balancing budgets. This is true for most western countries.
Given the current situation, I do not agree that "we need more taxes", but would welcome your clarifying exactly what you mean.
