Yimby vs Nimby is yet another divisive jingoism - simply putting tags on things and then using them as if significant.
The situation is more complex. The forces about housing right now are incredibly destructive. Rich people want to make more money by building expensive homes. In this case NIMBY is the correct solution. In other cases Rich People want to prevent affordable housing. In this case YIMBY is the correct solution. But blindly applying these terms provides a cover for a complicated situation. We have cults of personality, and now we have cults of Jargonism. Neither helps us.
Being outraged because lawyers don't want you to speak is great. The issues legal and housing issues are far more complex and important.
> Rich people want to make more money by building expensive homes.
Rich people want to make more money by blocking homes from being built, thereby driving up their property values and making all housing in the area more expensive.
You present a very simplistic view that does not begin to capture the complexity of what's actually happening in practice:
> Rich people want to make more money by building expensive homes. In this case NIMBY is the correct solution.
Why would NIMBYism ever be the answer here? What values does it represent? Allowing rich people to build housing for rich people means that the rich in need of housing don't take away more affordable housing. And when rich people are forced to pay for more affordable hosuing, what used to be affordable becomes unaffordable.
Ensuring that rich people's money goes to new building that doesn't hurt less rich people is the correct solution, if one values keeping housing affordable. One should only block that rich housing if one wants the existing housing to become more expensive.
