What can you do for your kids to help give them a leg up in the future

I have 2 toddlers and im terrified of what their future looks like. Are there things we should do to help give them some anonymity in their future... I think about the things my parents could have done easily 20-30 years ago that are a little harder to accomplish today. What are those things today that 30 years from now we are gonna look back on and wish we started for them.

Edit- removed the examples as for some reason …
