If the families and people that would benefit from this economic boost cannot afford to live in the areas being fed by these taxes, who is it benefiting? The people who already bring their own wealth? There is also the issue (especially in SF and now Oakland) of the effected parties disproportionately being minorities as well and that these changes in landscape are racially exclusive. I do admit to not having much knowledge of tax distribution in the Bay Area, however, but it is definitely a different situation than Detroit.
People leaving their homes in SF are not moving to other neighborhoods but to other surrounding cities in the Bay. This may be an issue limited to SF in particular, whereas other cities may have larger neighborhoods and boroughs that sprawl, many in the Bay are their own separate cities. This is where some more knowledge of tax distribution is needed on my part, but it's getting very difficult to be poor and even middle class and reside in San Francisco.
