Anyone is a lofty standard. Some is true, but you don't hear about the super smart guy who worked really hard but for some reason or another luck didn't go his way and then he had no safety net to fall on. I can take risks because although my parents aren't leaving me a trust fund, if shit REALLY hit the fan, I could always move in with them instead of starving in the streets. If you have nobody to lean on, risks seem a lot bigger when you have further to fall.
I actually know a lot of people who did that. They all got by. America at least is a very easy place if you're smart and hard working. That is not true in many parts of the world unfortunately.
A lot of people is still not anyone. I know several people on the other side of the coin who were incredibly smart and ambitious and resourceful and failed, with no one to fall back on, and now have some serious problems in their life. There is no doubt these guys would have bounced back a lot more easily if they had a trust fund to lean on.
I don't think anyone would claim that a trust fund is a disadvantage. But if the people you know are really smart, ambitious, and resourceful, then give them time. They're still just in process.
