As Millennials and gen Z become more mobile, what organizations and institutions will suffer because of it?

Investment clubs seem to have been traditionally location-based, but because people are a lot more transient due to their jobs organizations such as investments clubs will have to transition to being more virtual. To that point, I suspect that as Millennials and gen Z get older, they will become more settled. The question is, will they then be more likely to join investment clubs?

Taking a step back, how beneficial are investment clubs? Do people on average make more money than if they had invested by themselves?

What is the average age of an investment club member? How long have they been members?
