"if you consider spending on yourself now versus on your kid one generation later, you discount future returns at roughly a factor of two per generation". That is Alan Rogers theory. The problem is that it assumes senescence. Why spend on your kids, rather than your future self? Senescence. Senescence fairly simply and obviously explains most discounting. You typically don't transfer much wealth to your future self because you will be old then. Giving to your sexual offspring rather that your asexual offspring a generation might make a bit of difference if you hapen to be a species who is into parental care - but the main story about discounting is senescence, not kin selection - and senescence applies to sexual and asexual creatures aike.

Re: "one simple theory is that even though cultural evolution happens much faster than genetic evolution, genes still remain in firm control of cultural evolution".

That's often referred to as Wilson's idea that genes keep culture on a leash. However, looking at the possibility of runaway cultural evolution, surely that looks like archaic nonsense. DNA looks as though it is destined for the dustbin of history. There is no leash.
