[EX Q]: At the time of the fall of the Egyptian monarchy in the early 1950s, less than half a million Egyptians were considered upper class and rich, four million middle class and 17 million lower class and poor. Fewer than half of all primary-school-age children attended school, most of them being boys. Nasser's policies changed this. Land reform and distribution, the dramatic growth in university education, and government support to national industries greatly improved social mobility and flattened the social curve. From academic year 1953-54 through 1965-66, overall public school enrolments more than doubled. Millions of previously poor Egyptians, through education and jobs in the public sector, joined the middle class. Doctors, engineers, teachers, lawyers, journalists, constituted the bulk of the swelling middle class in Egypt under Nasser. During the 1960s, the Egyptian economy went from sluggish to the verge of collapse, the society became less free, and Nasser's appeal waned considerably.
[EX A]: How many rich, upper class were in Egypt in 1950s?

[EX Q]: A number of researchers (David Rodda, Jacob Vigdor, and Janna Matlack), argue that a shortage of affordable housing – at least in the US – is caused in part by income inequality. David Rodda noted that from 1984 and 1991, the number of quality rental units decreased as the demand for higher quality housing increased (Rhoda 1994:148). Through gentrification of older neighbourhoods, for example, in East New York, rental prices increased rapidly as landlords found new residents willing to pay higher market rate for housing and left lower income families without rental units. The ad valorem property tax policy combined with rising prices made it difficult or impossible for low income residents to keep pace.
[EX A]: What do a number of researchers think a shortage of is caused in part by income inequality?

[EX Q]: Throughout the Hellenistic world, these Greco-Macedonian colonists considered themselves by and large superior to the native "barbarians" and excluded most non-Greeks from the upper echelons of courtly and government life. Most of the native population was not Hellenized, had little access to Greek culture and often found themselves discriminated against by their Hellenic overlords. Gymnasiums and their Greek education, for example, were for Greeks only. Greek cities and colonies may have exported Greek art and architecture as far as the Indus, but these were mostly enclaves of Greek culture for the transplanted Greek elite. The degree of influence that Greek culture had throughout the Hellenistic kingdoms was therefore highly localized and based mostly on a few great cities like Alexandria and Antioch. Some natives did learn Greek and adopt Greek ways, but this was mostly limited to a few local elites who were allowed to retain their posts by the Diadochi and also to a small number of mid-level administrators who acted as intermediaries between the Greek speaking upper class and their subjects. In the Seleucid empire for example, this group amounted to only 2.5 percent of the official class.
[EX A]:
Native populations in the Hellenistic world were discriminated by what peoples?
