I agree that some of it is the NIMBY effect, but there are other reasons, too. California has legislated itself out of affordable housing. When we were building in the Reno/Tahoe area, the codes required special tweaks and additions that effectively doubled the final cost. For example, one of the requirements is the installation of hurricane ties between the foundation, sill plate, and lower framing members. They couldn't be just any ties, they had to be Simpson Ties (a brand) and that added at least $10K to the cost, and we had structural engineers tell us it was counterintuitive because the fasteners used to attach the ties were actually weakening the structural integrity. California codes also require an architect's stamp on virtually any change order and then they charge for inspections. The permits are sky-high already. In Kansas, you can build a 3-car garage for around $60K. In certain counties in California, that same garage would run over $200K, and the builders there are not the ones making out like bandits.
You'll never get California to (un)legislate all their building rules, so building costs can't drop.
But, back to the NIMBY thing. You cannot blame anyone for wanting to protect their neighborhood. The cost of a house is typically the single largest purchase folks make and they don't want to lose on their investment. In the video, someone wanted a zoning variance in a two-acre area to put in multiunit housing. That towering building would have stuck out like a sore thumb. I don't blame homeowners for not wanting it there. Plus, when you start talking about the homeless, you're talking about additional problems, because some of them just don't have the mental capacity to care for themselves in a better manner. There's a lot of mental disorder among the homeless.
Here's a question for you--are you prepared to allow a half-dozen homeless persons to pitch tents and live in your backyard? Because if you aren't, you really can't judge the people in the video who aren't prepared either.
That said, conservatives typically do take better care of their neighbors and the needy because they do it directly. My little community is small, very conservative, and very able to help those who come here and need help. We have an Adopt a Family program that we've participated in for about 20 years, and it involves purchasing all the food and gifts for a family in need for Christmas. Our Habitat organization has to advertise to try and find families that will take us up on the offer to build houses for them. The churches stand ready to take in the homeless and feed them, so the problems are dealt with as they occur and they never grow into the massive issues seen in huge cities.
The problem with Democrats--just my opinion--is that they want the government to do their charitable works for them, and government always $#@!s it up.
I agree with the schooling thing in the video--that's just not right.
