Time also plays a part.

When I was staying at home with my kids and poor as fuck, 4 people living on $15k, if there was gas in the car I could just take us spontaneously to the park, and my city has free music performances on some Thursday nights, if I have free time I can just make a last minute decision and go.

So now I have a good husband who earns $ and a good job, not rich but certainly more affluent than at any time in my life, but I am much less rich in time. Job takes a lot of it, more responsibility overall and less flexibility.

I don’t think spontaneity scales with money, it scales with free time once you have enough money. And that “enough” is not a lot.
