The benefits of urban life are supposed to a form of Utopia--an ideal community of equality in social, political and moral aspects. This should mean affordable housing, transport, utilities, and a fair wage and taxation system.
Dystopia means the opposite, such as quoted in the question. Crowding, crime, alienation, oppression, poverty.
An ideal vision for the future of urban life needs leaders/governments to envision, plan and fund a more equitable society. One example, with housing, is for cluster dwelling areas to include open spaces for enjoyment and sporting activities.
