I suspect the answer is, like most things, 'politics'.
So, to me, for instance, take the biggest problem the world currently faces - global heating.
I think everyone knows the two or three things we would need to do to 'solve it':
- carbon tax
- carbon capture
- energy reset/clean/green/conservation/etc.
But it's only partially 'solved', same as robocalls.
There are just too many people making too much money, having too much success, with robocalling to stop it.
