Critically examine the Marxist aspect of political economy approach to the study of comparative politics

Marxist approach to political economy makes the following points:

1. It has advocated that political inquiry is holistically and historically oriented rather than limited to segments and current affairs.
2. It should seek synthesis in the search for an understanding of social problems and issues.
3. The study of politics should be combined with economics.
4. Marxism in this context should be seen as a methodology rather than an ideology.
