(with apologies to Jonathan Swift)...it is worth consideration that all who embrace ethical veganism arrange their affairs that...upon their life's end all their resources be bequeathed to a vegan animal rescue facility/operation and/or vegan advocacy group(s).
A proposal that is a bit less modest: Why not configure society such that upon life's end all acquired resources revert to agencies/organizations created to equitably rebalance the distribution of wealth or whatever (this would include all living beings, not just human ones). That way greedy goobers could have at it but the deck would be reshuffled when they hit the floor/door. No more family dynasties, aristocracies, etc. I suspicion it would be fairly easy then to fund important things like animal protection, education, health-care, research, environmental initiatives and on and on. (of course if someone had beings unable to care for themselves that were dependent upon her/him...their needs would be addressed first).
Just some thoughts.
