The best description of employment mix in US cities is by "II and III"-

Statement II- The majority of workers are moving away from industrial jobs and toward professional service jobs.

Statement III- Cities are more focused on consumption and material goods than industrial activities.

Explanation:

As an economy progresses from developing to developed, it undergoes a sectoral transformation where the economic structure goes a transformative change. Since the US is a developed economy, its main workforce lies in the tertiary sector (mostly services sector) rather than manufacturing and other industrial activities.

Statement I- The statement is wrong since the majority of employment is from the services sector.

Statement II- As explained earlier, with the transformation of the economy, employment avenues move towards services (tertiary) and quaternary sectors.

Statement III- Due to increased disposable income of people and prosperity, cities are focussed on consumption, unlike developing countries where cities are the hub of industrial activity.

Statement IV- Crime in cities is high due to the high disparity of income. There is a high divergence of income between affluent and poor class which manifests itself in high crime rates.
