Don't let the perfect be the enemy of good enough. Inequality is a fundamental part of human existence, but I'd prefer that inequality to be as much as possible an expression of individual merit rather than a financial windfall as a result of parental success.
As I mention in another reply, your "inheritance" is what you get while your parents are alive.
The goal is to prevent persistent, cross-generational inequality. High inheritance taxes simply won’t accomplish this. Or even come close.
The only policy that had ever achieved the sort of field-evening you want is a very strong public sector.
Providing quality education, job, opportunities to everyone (or at least lots of people).
A good example is Sweden. Sweden had massive asset-inequality. A handful of families are massively wealthy, and the successfully pass that wealth down generations.
Yet Sweden had little income inequality, because of their strong public services.
I simply hate the unfairness of this particular form of wealth transfer: the winners hit the jackpot without even buying a ticket.
At the very least the dead guy will pay for them to go to Harvard, arrange the appropriate internships, etc.
It’s very possible to preserve a class system without actually transferring wealth to your children upon death.
Just use your wealth and money to make sure they’re set before you die.
Easy-peasy.
Just look at the many children of still-Alice billionaires. They’re not hurting.
For example, Warren Buffet announced he was giving away all his wealth, created a foundation that possesses most of his wealth, and named his son as director.
Not rocket science.
And that doesn’t include the affects of private tutors, nanny’s, quality education, etc.
