I think that's a bit of a myth, at least in a global scale. In Europe there's a lot of old money, or sources of income that only later generations can rip the benefits of their ancestors. The most common example in my country is people that sustain a lot of their wealth with cork. The thing with cork is that it takes decades to build up, and a large area. Basically people are living from their great+ grand parents buying small patches of land over many years, that had the trees already planted (or that just grew in the meanwhile). And I'm pretty sure this reality is probably also common across the Mediterranean region.
