I'm always amazed at the distaste that the idea of generational wealth receives here. For me, it is the foundation stone of my well-being. My great-grandparents scrimped and saved in the depression, and passed on a small nest-egg to my grandparents. They scrimped and saved and passed on a slightly larger nest egg on to my parents. My parents lived and raised me in many years of poverty, saving what they could, and then inherited the wealth of generations. I expect that I will inherit that nucleus of the family's fortune in due time, and will do my utmost to husband it and grow it in trust for my descendants.
Whatever I achieve in this life is not my own, it is the culmination of the efforts of all the generations that put me in position to do what I do, and a legacy to leave to all the future generations of my family.
At micro-economic level this makes sense, at macro-economic level it reduces economic mobility. In countries with no artificial taxes on generational wealth the richest families of 2016 are likely to be largely the same as richest families of 1916 and richest families of 1816.
As their wealth is typically preserved via real estate and
land ownership, there's a politicial motive to decrease the cost of that, so economies also suffer from high barriers to entry and need to inflate taxes on something else to pay for the government services.
Repealing estate tax would work when combined with higher property tax rates or land value tax, but is rarely politically doable, as well-connected political families and large landowners tend to be the same families.
I value the spirit of passing something on, but I despise the inequality that emerges from repeated iteration.
The value lies in long term thinking, sustainability. A farmer can either maintain the soil, carefully rotating crops so that it will be able to feed future generations as good or better than his predecessors, or he can go for the agricultural equivalent of strip mining and move on to the next plot when the previous one is depleted.
But when you replace the soil with fungible assets, all that long term thinking benefit goes out the window. Sticking to the farming example, repeated slash and burn farming will only encourage more of the same, as long as there is something left to burn. Larger operators will grow faster than smaller ones, and after a few generations, when there is nothing left to burn, the descendants of those who burnt the most will employ the losers to tend the desert.
