17th-18th century social strata?

Good morning! I am trying to get a feel for social and economic standing when reading tax assessments and probate records and am wondering if there is any document that gives 17th and 18th century equivalents. Or is there a general current value for riksdaler/marks for the same time period? An example is a record I read yesterday for Hordaland in 1707 of an estate that included 10 laup, as well as an annual salary of 4 riksdaler for the position of sheriff. How does this translate into present day values? I am also trying to understand the social strata of the 17th century, and would appreciate any suggestions for articles to read that could give me an idea of what constituted farming class, merchant class and upper classes (landowners and nobility) for the same time period. Thank you to anyone who can give me suggestions of documents to read about this!
