Lol, Typical Trump line of reasoning. Am glad you did not claim foreigners nailed Jesus to the cross.
Back to my first solution then. Forbid the foreigners buying up real estate in blocks drying up the existing real estate inventory!! It's NOT just the Silicon Valley or Bay area or San Francisco those big cities that has this kind of housing crisis; it's the ENTIRE California that is plagued by those foreigners overseas chalking up the prices by their massive buying.
They take away our jobs and then leave us homeless in our own country, that's ABSOLUTELY ridiculous!! I tell you once the foreign buyer tax was levied in Vancouver in Canada, the result was IMMEDIATE!! All the foreign buyers moved away! And all the real estate agents that were making millions at the expense of local residents all cried foul. And now since nobody is buying the properties, the price dropped down like 10%. All those idiots who bought, they all lost money!! LOL And finally a chance for local residents to own a home.
