Start in my backyard
NIMBY's know what they don't want. SIMBY's know what they do want and take good ideas and actively support or try them at home or in their community.
SIMBY - stick in my back yard.
The SIMBY crowd go to city hall and get everything they want including parks and recreational facilities, libraries, schools, museums, mass transit, street landscaping, and other community amenities.
I guess it's a little refreshing to the politicians to have a break from the NIMBY who are not happy with anything.
