I am reading the book by Steven LeBlanc and Katherine Register, Constant battles, (2003). It is about history of warfare, but on p. 165 I found the mysterious sentence:
For example, rules can be passed and enforced restricting marriage to people with enough wealth to set up a household, as was the case in England,
Can anyone explain what they mean? I've never heard about "rules restricting marriage" on the basis of wealth, in England, or any other Christian country. Unfortunately they do not specify the time period. They mention existence of such rules at least twice in the book, as something known, without giving any further detail.
Edit. I summarize the prevailing opinion in this long discussion: the authors made this up. No such rules were ever "passed and enforced".
