Coaching the opposition. That's only relevant when the opposition is hopeless lost in the weeds, is in power, and is running society into the ground.
The problem is that there are two major forms of capitalism, one based on classical liberalism and the other on neoclassical liberalism.
The first is laissez-faire and the second is neoliberalism.
These are greatly different and conflating them leads to confusion.
Perhaps most significantly, as Michael Hudson constantly reiterates, classical liberalism in economics was about reducing and eliminating economic rent, while neoliberalism based on neoclassical economics is based on rent extraction.
Classical liberalism was about reducing the role of government in the economy so that economic rent would be competed away in efficiently operating free markets, so that profit would be based on productive contribution rather than market asymmetries.
Neoliberalism is based on using institutional arrangements to favor capital "because growth," the assumption being that growth is the higher priority and growth is the outcome of capital formation, so that capital must be favored as a factor over other factors, namely, labor (people) and land (the environment). So the formula becomes "capitalize gains and socialize losses." And the means is increasing asymmetries institutionally through capture.
People are beginning to get this now, at least inchoately, owing to the poor results they are experiencing, and voters tend to vote their pocketbooks.
The challenge is to debunk the myths based on conflating classical liberalism with neoliberalism, along with educating the public about how economies actually operate in the real world.
These challenges are getting easier to meet meet in that an increasingly large number of people are realizing that they are holding the short end of the stick, and many of them are young people that will be around for a while and voting. It is also leading in a resurrence of interest in Marx among them, since it is increasingly obvious that these issue reduce to class struggle.
There's class warfare, all right, but it's my class, the rich class, that's making war, and we're winning. — Warren Buffett, as quoted in "In Class Warfare, Guess Which Class Is Winning" by Ben Stein, in The New York Times (26 November 2006) [Wikiquote]
Dillow's post is worth reading in full. It's import is not limited to UK politics and the UK economy. As usual he provides useful links regarding the points he makes.
This also shows how bound up economics is with politics.
