If no sources exist, then you must accept making claims such as this would 'lower savings rates' are simply not backed up. Maybe it will... maybe it won't.
So what if there is no reason to own property beyond a certain age? Even if we take this claim as true... that doesn't explain if this is a good or bad thing.
> then you must accept
I don't, because this argument is nonsensical (I mean your point about source specifically). Unless you disagree with some of the core principles of modern economics (not saying that you have to agree with them..) that would be the most obvious outcome.
> So what if there is no reason to own property beyond a certain age?
Well that would mean that the savings rate would go down (for better or for worse).
You've not established that your suggestions are core principles of modern economics or derived from them.
For example, you are asserting there would be 'no reason to own property beyond a certain age'... which isn't supported, and then jumping to the conclusion that that would lower savigns rates.
None of this is clearly true, just supposition.
> which isn't supported
The general consensus amongst most economists is that humans behave in a rational way? Not spending all the wealth you before you die would be irrational if your children won't inherit it.
Of course in reality that's often not the case especially these days so it might not be sufficient enough.
> clearly true, just supposition.
Well by such standards every discussion on any policy that hasn't been tried is meaningless because there isn't any empirical evidence.
