Narrowly interpreted, and as originally conceived, Socioeconomic Democracy (SeD) is a theoretical model socioeconomic system wherein there exist both some form of Universal Guaranteed Personal Income (UGI) and some form of Maximum Allowable Personal Wealth (MAW), with both the lower bound on personal material poverty and the upper bound on personal material wealth set and adjusted democratically by all participants of society.
The two fundamental socioeconomic system parameters that are, with SeD, to be determined democratically, enjoy a long list of advocates, including Paine, Jefferson, extending back to the ancient Greek thinkers and up to the present global quest for improved, more just economic systems. Socioeconomic Democracy adopts this well established tradition and simply democratizes the possibilities faced by any society. This is accomplished by employing a central result of public choice theory, i.e., median value of participant preference distribution of an amount in question is the democratically desired amount, with single-peakedness and majority rule. Socioeconomic Democracy thereby inaugurated public introduction to and adoption of quantitative democracy.
Many theoretical aspects of SeD are suggested by its four possible democratically established variations, namely, some amount of UGI or zero UGI along with a finite MAW or an infinite MAW limit. The analysis of these four different, yet all fundamentally democratic, socioeconomic subsystems provides considerable insight into the unresolved problems of many past and present-day politicoeconomic persuasions, as well as theoretically resolves the dilemmas momentarily inhibiting the realization of these two important socioeconomic system operating limits.
A well developed body of knowledge already exists regarding Socioeconomic Democracy. Crucial matters such as economic incentive and self-interest, financial benefits and costs, theoretical justifications, politicosocioeconomic feasibility, practical political approximations to the ideal theoretical model, comparative relationships between SeD and various religions (both spiritual, e.g., Zakat in Islami economics, and secular extinct or extant politicosocioeconomic systems), implementation considerations and the desirable impact of SeD on numerous serious societal problems have all been explored. It can safely be anticipated, however, that far more insights into Socioeconomic Democracy await future realization.
More widely (and loosely) interpreted, Socioeconomic Democracy refers to or includes that larger class of socioeconomic subsystems wherein other significant societal system parameters are democratically set. For example, possibilities include the societally desired magnitude of a maximum wage/income; a minimum wage/income; max-to-min ratio of incomes; amount of personal wealth and/or income below which a participant of a democratic society is not subject to any wealth and/or income taxes, etc. The "corruption" of the original specific meaning of Socioeconomic Democracy to this more general application of quantitative democracy, while perhaps regretable, is no doubt inevitable.
The first book-length description of Socioeconomic Democracy was published in 1972. Both as a specific system and as a general perspective, Socioeconomic Democracy clearly refers to a postmodern and future-oriented political economy, as opposed to past, present and backward-looking political economies.
