The phrase 'It distorts economies because it punishes productive people for being productive' in relation to progressive taxation does rather assume that people who are more productive get paid more. This does not neccesarily hold true, even if production is defined as contribution to the creation of wealth. It is certainly not true if production is defined as the creation of value.

In addition, the adjectives distort and punish seem rather emotive. It can be argued that people paying higher rate taxes have a duty to contribute to the economy and nation more than others. (such as one-nation toryism)

>Other purposes might include redistribution 
>of income from the rich to the poor,

If the state appropriates money for the exact opposite purpose (enrichment of the rich at the expense of the poor), is it still tax money? - n8chz

... might include ... - think it´s not necessary.
