What aspect is highlighted in the argument against the Fit thesis concerning inheritance?

The argument against the Fit thesis concerning inheritance emphasizes that traditionally, inheritance practices favored the eldest son, indicating a system of primogeniture. This meant that only the firstborn son was entitled to inherit the majority or entirety of family assets, while younger siblings, often daughters, received little or no inheritance. This practice reflects broader social structures and norms that favored male lineage and perpetuated class distinctions within families and society.

The Fit thesis posits an ideal of resource allocation that might suggest a more equitable inheritance system; however, highlighting that only the eldest son received the majority of assets challenges this notion. It reveals how social and economic structures can privilege certain family members over others, thereby impacting social mobility and the distribution of wealth across generations.
