I'm a bit further on the same path (4 year old). Here's what I've come up with:

competence is what I try to teach. Try, try and try again until he'll get it. Small things at first, but (hopefully) he gets the principle. Legos are great at this.

Additionally I try to teach that it's not wrong to defend yourself.

The issue with is, as far as my personal anecdote is concerned, that competence doesn't translate across all activities. Me being good with figuring out Legos, video games, or programming doesn't translate to me being good with cooking, socializing, music, etc.

Furthermore, I find it completely reasonable for someone to care about the long-term financial focus of their children. I find this to be the second best antidote to all the uncertainty and fear older generations leave behind to the new ones.

The first best would've been to actually give a damn and make a stand to what the powers-to-be force you to accept as the new norm as if they're the force of nature that make decisions on how the 95% of the world's population must adapt to.

How does that avoid the bullied from shooting up their school bullies while at school under the guise of defense?
