Noel Pearson's 2010 John Button Oration (highly recommended - listen here) got me thinking about the relationship between urban plans (such as Melbourne 2030) and the relationship between it and various economic classes (especially the middle class).
To summarise, the intellectual middle class says what ought to be built and the capitalist landowning class goes off and builds, taking a risk in return for a possible profit. While planning regulations (largely drafted and interpreted by the middle-class) have some influence, the capitalist can apply the ultimate sanction, ie choosing not to build if they see no profit. This puts a limit on the strictness (or 'unworkability') of planning regulations, otherwise undersupply will be the result.
Urban planning can be seen as a tussle between a portion of the middle class (either as bureaucrats, academics or activist residents) and the capitalist upper class. The working class has a role as consumers through housing and shopping preferences. There is thus a consumer-producer relationship between the working class and the capitalist (if buying a project home for example), but the relationship between the working class and middle class is very limited.
I previously described Melbourne 2030 as a plan that favours the grouping of certain land uses (cafes, galleries, educational establishments and higher density housing) around transport hubs.
Favoured land uses represent the interests of the humanities-educated portion of the middle class plus some perceived working-class wants (or should haves). The latter being desirable to foster 'diversity' and 'inclusion'. Certain other land uses, such as bulky goods retail, fast-food and (especially) light industrial, are not part of the academic's world so tend not to feature prominently in their plans. Ignoring them does not make these uses go away, instead they go to the periphery without public transport or pedestrian access (Tullamarine and Laverton North spring to mind).
Lacking capital, the interested middle classes (especially academics, bureaucrats and council planners) use plans to advance what they see as the public (or is it their?) interest against the capitalist landowning class. To the extent that they are implemented they advance the former group's quality of life and aesthetic sensibilities. A Marxist analysis would also see city planning as part of a broader contest between intellectual and capital, with each group wanting their strength to prevail.
The middle class, even its humanity educated portion, is not homogeneous. As often played out in The Age, it is deeply split on the question of housing density.
There is what I would call the 'technocratic' or 'urbanist' middle class which favours higher densities for a more compact, less sprawling city better able to be served by public transport and other services. A substantial proportion of this group would have lived in or visited overseas cities with higher densities than ours. Some may work in planning. Their arguments are both environmental and economic, with the economic one being an echo of Le Corbusier's vision of cities as being 'machines for living in'. While it is another debate, this group may be quite relaxed about the city's capacity to house a higher population (though being quite well paid they will always be able to afford to live in the city's 'better' areas).
There is common ground between this group and developers (whose profit increases with density, since fixed costs can be spread across more units). The developers need this group to argue their case, while the urbanists need the developers to allow their preferred city form to be built.
Opposed to densification (at least in their backyard) is another faction of the middle class. 'Suburban protectionists' are less enamoured with high-rise and go by names such as 'Save our Suburbs'. This group professes a wish to preserve their neighbourhood's quiet streets, leafy verges and an always-free parking spot in front of the house. High-density is also thought by residents to be associated with crime, especially if 'outsiders not like us' (eg public housing tenants) move in. Hence NIMBYs ('Not in My Back Yard') are vulnurable to accusations of xenophobia or selfishness. While another (though related) debate, protectionists often question the benefits of continued population growth in our big cities, and may propose decentralisation (for others of course) to lessen pressures on our bigger cities.
As homeowners,suburban protectionists' key economic interest is their house value.
This is especially so for the middle-class.
The biggest determinant of wealth in Australia is whether you live in your own home or rent (those who both rent and invest are a small, savvy minority). Poor people are by and large not homeowners, so values are irrelevant to them. Then there's the rich. While they may live in nice homes the genuinely financially independent hold most of their wealth (80 - 99%) in other assets, such as their own businesses, rental properties, shares and the like. In contrast the middle-class person's home is their biggest asset, with most of their other wealth (superannuation) being untouchable until retirement. Hence concern that a development may lower house values is quintessentially a middle-class concern.
The relationship that high density leads to better public transport is also disputed. 2004 - 2008 for instance saw a train patronage boom but no commensurate service increase. And if higher traffic slows buses and trams, their efficiency will fall without priority. Academic support (in the sense that successful public transport is more a function of service planning than density) is offered by Paul Mees of RMIT.
To conclude, planning and the argy-bargy that goes with it, is a game between a protectionist middle class and a capitalist class (legitimised by a technocratic middle class). The middle class has brains but no capital. The capitalists have money and can co-opt as many middle-class minds as necessary. The middle-class itself is divided. Hence we generally get a largely market-oriented plan with some urbanist features such as denser activity centres and protectionist features such a (movable) urban growth boundary.
