I have a property tax beef! Lower Value Homes!

Our homes has lost much of their value says the government and people can also see it in home sale prices. This is the beef I have, why has not the government re-value our homes and lower the property taxes we pay?
With year-over-year home value losses continuing to accelerate, most areas of the country will see housing values get worse before they begin to stabilize.

What do you think, should we still be paying the same amount in taxes with our homes worth less?
