@janneke rats, I left out the most important and pertinent bit: that certain behaviors are more difficult for some than for others, and that it's not "just" a matter of budgets, but also of different perception of certain difficulties, and even actual personal differences that make certain behaviors more or less difficult. kind of obvious, but it took me a while to realize and then to formulate that, as I found myself unable, for various reasons, to engage as deeply with other causes as with my primary cause
