I don't think that point holds much water, as the mega rich person in question is only able to become mega-rich off the back of the workers (who are educated by the state & use NHS beds), paying taxes for the NHS/education system doesn't really have any connection if the person needs it or not - it's a systemic cost, part of the cost of keeping a healthy educated population able to garner the wealth required which in turn drives the demand for the goods & services the mega-rich person is selling.But it logically follows that the sect of wealth you are referring to are more likely to use fewer public services. Since when did the mega-rich (and let's face it, if we're talking 'dynasties' here, we're not talking upper Middle England) go to state schools or wait for NHS beds?
I'll use an example.This all sounds very theoretical to me. Inheritance is not at the expense of wider society as it already has been taxed in some way, shape or form (usually multiple times). Maybe I'm being thick here, which is quite possible, but I don't understand what kind of short-termism you're referring to as these kinds of societal directions and decisions are not made by individuals, they're made by policy-makers; at least at the system-wide level that you initially refer to.
CEO A in corporation X pollutes the environment (air pollution/sea pollution) which is likely to have disastrous long term consequences for the population to maximise profit.
Wealth left to his children will pretty much protect them from the fallout of said choices.
Or another example,
Politician B, removes social welfare knowing that due to his wealth - his children will never have to rely on the welfare state as he's able to protect them from any accidents/poor life choices which would normally result in the average person ending up in the dole line or relying on disability for sustenance.
Wealth enables people to protect future generations from the impact of changes which effect the general population - as the people in positions of power are also wealthy - we have a social conflict of interests.
