The modern city people prospecte the future would be better with the city experience accelerated growth and concentration, though they have to face many difficulties to live in the metropolise.   

    Credit economy should be responsible for the revolutionary change of city growth. People were in a complicated web of inflated and capitalization. Credit used to purchase land and building is a force of growth. In addition, people don’t prospect their future income from salary, but from property.

    In this process, the city faced a constant migration into metropolises. In turn, income from investment, which was people’s aim, depended upon an ever-accelerating migration.

    Actuary, the gains from the growth and intensive use of city land have been imaginary rather than real. Though the accelerating growth of urban can’t continue definitely, people have based the wealth upon the prospect of continuous growth, expansion and congestion. In sum, people placed their eggs in the basket of “progresses”.
