OK. Let's go back in time and tell everyone in the 1800's that it's okay not to abolish slavery because "people don't really care buddy".
Let's just never change anything in the world because whatever we have is good enough, because "people don't really care buddy".
That attitude is literally cancer to society, and has been used to justify sticking with the status quo. I mean, why bother reducing our carbon emissions? It's easier to do nothing and just stick with the status quo. We'll let other people in the future deal with it, because we're too lazy and/or incompetent to bother.
Anyone that has your attitude is basically human scum, and contributing the degradation of the human race.
