You could almost eliminate your property taxes, if you eliminated the service of educating children.
^ I have harped on this for years.
My main beef....veterans. They should never have to pay tax on anything. Land, homes, food, medical, including dental, services , meds, vechiles, insurance...
Of all the waste and fraud of Americans tax dollars, there would be more than enough in the support of appreciation to our vets , being top priority. NO vet should ever be homeless, or donation organizations needed ( some are wonderful , of course ) , to provide for them what should be a given . The best of everything. They've already paid ...some still paying with their health.
Other than that, a slew of others are already mentioned above.
