The solution to the rich

In a comment piece on The Guardian raging about the horrible way that people that do lots of work get lots of money. The stand out quote was this one:

"Future historians are unlikely to look back with approval if the longest-serving Labour government presides over the biggest maldistribution of incomes."

How do they know that this is a maldistribution of income? These are the rates set by the market, the best mechanism known for ensuring the correct distribution of resources. Does The Guardian have some secret economic formula for calculating the perfect way to distribute resources, and they are just keeping it to themselves out of spite forcing the rest of us to rely on imperfect method od markets. Or are they just speaking out of their colective arseholes.
