Electoral reform, at all levels. Start with municipal governments by offering tax dollars to help with the transition and to educate citizens. Once a municipality has successfully held their first election under the new system, they get some more money to continue their education plans, then move up to provincial, federal, etc.
Boost healthcare. The state of all healthcare systems is shameful. Bonus transfer payments for strengthening the healthcare system with higher wages and benefits, lower wait times, more equal access to care, and fewer people without family doctors.
Get serious on the environment. Nothing else matters once you can’t drink the water and breathe the air. Stop subsidizing carbon, collect carbon taxes, and direct the collected money back to individuals. Big rebates for energy efficiency projects, electric cars & charging.
Kickstart housing. It’s not rocket surgery that cities and suburbs need higher density housing, with accessible public transit nearby.
That’s just off the top of my head…
To add to this, self-hosting is also best when you minimize everything - limited service, with limited functionality, on dedicated hardware that doesn’t share access to your internal network or storage. Folks who use point-and-click apps to install a half dozen unauthenticated docker containers, all open to the internet, running on the same PC they store the only copy of their family photos and music/movie collection on… make me crazy.
