This is inarguable.
> The left prefers inefficient redistribution.
This is an obvious strawman. The current inefficient solution is a compromise between the left (who want the government to help the poor) and the right (who don't want the government to help the poor, but can be persuaded if you mix in enough penalties for perceived sin.)
In order to have an efficient solution you need a majority of people voting to agree on what the goal is.
That's not quite true; just they want the main beneficiaries of redistribution to be the bureaucratic class rather than the working class. What you see as inefficiency (in terms of money reaching the end recipients) is in fact, the actual design doing what it was intended to do. Ideally (for them) ALL the money would go on civil servant salaries.
