Let’s see…may I draw a different timeline?
10,000 y.a. – City or regional government based on permanent stratification based on ‘divinity of the ruler’ prevails. Economic system is largely barter + protectionist (everyone is taxed and the divine ruler enjoys the proceeds in return for which he declines to kill subjects). No clear distinction between justice system, law enforcement, rekigious belief system, and the putting down of insurrection.
5,000 y.a. – Beginnings of universally applicable legal codes with specific punishments for infractions. Expansionist (imperial) government tendencies. Beginnings of formalization of units of trade (gold, certain gemstones, etc).
2,500 y.a. – Coinage in use; Imperial governments, local rulers, vertical hierarchy in permanent stratification. Elaboration of religious belief system as explanation and justification of power structures and social laws and mores. Occasional and intermittent democratic processes including election of representatives and voting on decisions. Some structures for providing services for the direct benefit of people other than the rulers.
1,000 y.a. – Beginnings of rejection of ‘divine right’ of rulers; increasing codification of laws and beginnings of codification of processes for creating laws.
500 y.a. – Beginnings of the ascendancy of knowledge and wisdom as the justification for the possession of power and authority. Beginnings of challenge to the religious-based explanation of the status quo.
250 y.a. – Expanding philosophical belief in democracy and equality leads to movement away from permanent vertical hierarchies in favor of representative elected governments. Expansion of literacy and availability of media enables increased awareness of and cries for participation in decision-making. Governmental structures justified on the basis of service to citizens. Taxation justified through representative participation in their redistribution on the part of the taxed. Increased support for freedom of religion and isolation of religious structure from official governmental decision-making structure.
125 y.a. – Expanding belief in basic equality leads to decay of category-based social status systems. Slow but perpetual global increase in democratic tendencies of governmental processes. Continued increase in interconnectedness and informedness of peoples.
50 y.a. – Abstraction of units of exchange from physical commodities; beginnings of electronification of economic transactions. Still more movement globally from vertical hierarchical to more democratic forms of government. Redistributive economic tendencies result in progressive tax structure. Global economy comes to dominate national economies with resultant political global thinking becoming more commonplace.
10 y.a. – Accelerated changes in rapid electronic communication with increasingly democratic participation in media content; electoral government increasingly controlled by mass opinion; immediate up-to-the-moment coverage of governmental processes available to large segments of population at will. Decentralization of decision-making and economic control bases. Redistributive economic packages move away from charitable and towards remedial formats.
The Future – More movement away from the vertical hierarchy as the decision-making structure of choice. More decentralized multi-focal ways of doing things on an ad hoc and increasingly flexible basis. Increasing direct involvement of people in govermnent especially via electronic interconnection.
