But given that a universal cure for aging necessarily requires universal distribution of that cure, isn't it worth asking if you're putting the cart in front of the horse here?
Once you have the effective cure, it will likely be economically a no-brainer to implement, because a whole lot of illness of old age will just go away. It's essentially a self-funding cure that drastically reduce the cost of healthcare.
However, a cure for aging will not be solved tomorrow, maybe not even a decade. It is a long term investment.
The solution to the homeless isn't economically complicated. It doesn't require us to keep at a problem for ten years. It is strictly a matter of political will.
It isn't even a matter of practical concerns, because we live right now is unsustainable economically and financially.
