I think once a year is not enough as things change so rapidly these days. If you did it on, say, 1st Jan but things changed on 2nd Jan you'd have a whole year of paying too much. Every six months seems like a wiser course of action.
Money is broken.
I agree, and many people are too, some due to things outside of their control and some due to their own stupidity. As I said in another comment on this post, I do not think anyone really knows the answer/solution to the problem and if they do they have a reason not to share it...also, no one seems committed enough to do what's required to fix things.
We have a famous economist in my country, Willem Middelkoop, he has predicted a great reset long ago, and I thinks that's what already started, the debts of countries pressing so heavily on everything, forcing them to print more money but that's only making things worse - the revaluation of gold is the answer and because of this, everything governments can't make more off, rise in value.
I think you're right on the 6 months indeed when things change so fast
I'm hoping there's a heap of better decisions made moving forward as the pressure on most people is mounting. Societies' focus seems to be on the wrong things I think.
