It's not really a problem as far as suburbs go: those who want can certainly live there as long as they consider them fit. If suburbia is a bubble, it'll come down crashing eventually. If there's something to change with regard to the suburbs is that we should distribute the costs of living in a suburbs vs cities fairly. That is suburbanites should be paying much larger portion of the costs of public infrastructure and roads that stretch dozens of miles out to the countryside and are of no use except for suburbanites themselves. However, there's a much more serious problem related to the effects of suburbia. The fundamentals of current city planning and urban design, largely borrowed from the Garden City utopia, for the suburbia are so detached from the reality of urban development in cities that the greatest danger is in blindly applying these incompatible principles to the urban environment and, in effect of doing so, crippling the real fundamentals that actually govern a vibrant city life. We are killing the whatever health our cities might still possess by making them more fit for automobiles, segregating different uses into different zones, and doing huge disruptive redevelopment projects that wipe out and reset to zero big parts of city neighbourhoods. The result from this is be the devastation of cities by applying governance and design principles incompatible with city development--which has already been going on for decades--which effectively leaves people only the suburbia. Such a monotonous development is bad for the survival in general as is anything that lacks diversity. Think of Windows viruses versus virii for other platforms. Such a big disruption that could wipe out suburbia for anybody but the richest of the people is the rising of the price of oil. The oil price has already reached levels where daily automobile commuting from the farthest backwaters of suburbia becomes an actual economic obstacle. If, or when, suburbia fails, I'd like that we would still have cities where to retreat.
