True, but then you have to evaluate the value of having a deep skill versus a wide range of xp. Usually, it's a feat in itself b/c starting things often require money, which is difficult to obtain with no deep skills (unless given/inherited).
I'm more of the opinion that no deep skills is no skills at all. Similarly, a wide range of experiences from a blank slate without the necessary effort to connect the dots might as well be no experience at all.
Often an inheritance comes with an upbringing full of entirely different experiences, culture, and values from those who do not inherit much if anything. Deep knowledge and skills are naturally imbued into the next generation without much deliberate effort despite the fact that someone did put in much deliberate effort to manifest that situation. Every lineage begins with someone who had to learn it all the hard way.
