not necessarily, it would make sense for example for it to be carried out on the NHS with regards to the risk of certain diseases
as for elites, there are already differences between different social classes etc... if anything something like this, if widely available, could achieve the reverse
I mean I think we're still talking about editing/making minor changes, it isn't like you can have a complete re-write - currently a kid born to two low income, low IQ parents will be more likely to have a low IQ and have a low income themselves (not that IQ is a great measure in general but it does seem to have some predictive power w.r.t success and is partially inherited) - might be better to increase the chances that the kid is a bit taller, bit smarter etc.. and give them a better shot at life
there are potential metal health benefits there in giving people a better shot at life, reduction of suicide etc.. etc..
if there is some potential genetic element increasing the chance of obesity then that isn't just a cosmetic/elite thing but can have knock on effects on health, mental well being
I guess the other thing is that if it isn't allowed/widely available here then the elites will still have access through traveling to some other jurisdiction where it is allowed - for example I know of someone who traveled overseas with their partner for IVF because they wanted a girl for their second child
