profits and tax revenue? how about more housing for those who need it? or should we prevent housing for the 500,000 americans who don't have it because of tornadoes?
You would scream if those homeless died in a fire or tornado because the building lacked protection.
The two staircase rule increases costs, but not by that much - any place that allows building housing doens't have a homeless problem. That isn't to say there are no homeless people - there are many - but they are homeless because of other issues (mental). In California the homeless often are otherwise normal people who cannot afford a place to live despite the ability to work a job. Where I live you can rent a new two bedroom apartment in walking distance of Burger King that pays enough to afford that apartment and leave enough leftover for food - it won't be a great life, but you can live on one income (and since most people live as a couple that second income can buy some nice things)
This is what's called a false dilemma, pitting two non-mutually exclusive options as an either or situation when they're actually not opposed to one another.
We should get to reap the benefits of improved fire and personal safety and build more housing.
