Redistribution doesn't need to increase productivity, it suffices that it increases consumption for the economy to grow, if that's your only goal (it isn't the main goal for me).
Basically if you have the same amount of money in economy, but you double the number of transactions - economy will double too (assuming same distribution).
Money naturally accumulate. If you redistribute it - it starts moving again, and with each transaction something is produced.
That's why redistribution usually increases GDP.
But - the goal shouldn't be growing economy. The goal should be preventing oligarchy.

It also raises prices until the same amount is done. A plumber might work extra hard when he gets more work than normal, but will burn out if he continues to work like that so he raises his prices until he has to work just like before.
