| Taking your question at face value. Meritocracy: A system in which advancement is based on individual ability or achievement. If you think the most able individuals are creating and running the largest organizations, and know whats best for those organizations, why would you want the state to allocate those resources upon death of the individual? Also, most people have a time span much greater than their own life. I know I do. If I knew I wasn't able to leave a better life for my decedents, I wouldn't work as hard. If you have a wealth creation mindset (wealth is created) then this would be devastating to productive individuals |
If wealth is large enough, then useful incomes can be maintained in perpetuity - meaning the great, great grandchildren are still living off of the wealth created centuries ago.
The latter case was common in Europe, but relatively rare in the US due to the estate tax. Historically, landed gentry were rarely bastions of wealth creation and innovation - and are usually more focused on fending off threats to their inherited wealth than creating more wealth.
