Do we need a Prop. 13 in Utah?

Whenever I suggest Utah already has mechanisms in place to keep property taxes reasonably in check, I get hammered by readers who say what we really need is something like California’s Proposition 13, which went into law 30 years ago.
Now the Utah Taxpayers Association, in its latest newsletter (find it here.) does a comparison that shows Utahns spend less on property taxes, as a percentage of their personal income, than do people in California.
Utah has a so-called “truth-in-taxation” law that forces governments to declare any increase in revenue from year to year as a tax increase and to hold well-publicized public hearings. The state also grants a 45 percent exemption on your primary residence and has a provision to help the elderly.
California’s Prop. 13 locks in a person’s property tax until he or she sells the property. As the association asks, why should a home owner’s obligation to pay taxes for police, fire, schools and transportation be based on how long they have lived in their current house? And why should young home owners and new residents bear a disproportionate share of the tax burden?
No one likes property taxes, but we all like the services they provide. Utah’s fair-market valuation system seems a lot better, and cheaper, than anything Prop. 13 has provided.
