Why just one group afforded protection?

Why just one group afforded protection?

The state of Illinois may eventually disintegrate from the impact of its unfunded pension liabilities. The state can do nothing about it, according to many sources, because the defined benefits for a select group is protected by provisions of the state Constitution.

Can anyone identify any other provision of the Constitution that singles out a specific defined and limited group of citizens who benefit from a similar protection? In what other state(s), does the same level protection occur for a similar group or any other group?

Why has no one ever challenged this protection under the federal Constitution? It seems contradictory to the principal of equal protection for all to carve in granite a provision for one group, particularly where its application has and will continue to create a hardship for all other citizens that the constitutions, state and federal, are designed to protect.
