I don't think the two points are orthogonal, I think they're complimentary - please don't look for conflict here where I'm simply trying to reflect on multiple ideas. It could be that folks with higher incomes have a much higher expectation of quality of life, in terms of outcomes and activities for their children, it could be that people with higher incomes get greedy. In either case, an lesser cost of living might give more of them. Of people you know with higher incomes, why do they choose not to have kids? Again, its less than a 30% difference between the highest income and lowest income. The difference between the middle incomes and the lowest income is less than 15%. Simply saying that there are more factors at play, which I don't think is controversial.
