Because it is an untrue statement
No money = suprisingly enough, straight to jail.
In both cases it’s more problems, it’s just that most money problems can be fixed with more money.
More money = more problems.
No money/little money = problems
I would argue that the relationship isn’t at all linear. Just take a look at the dunning-kruger curve or the hype cycle curve to get an idea how wildly these things can fluctuate.
You have it. You could also say that the graph is linear, but with different zero values (“problems” has a bottom of N > 0), but if we’re judging from IRL, it’s more like a parabola.
I like to think of it this way.
As your debt grows, your problems increase very gradually, maybe even asymptotically. As your wealth grows, your problems increase roughly linearly, but the slope is steeper than with debt. In between the two, there’s the sweet spot with the least amount of problems.
