I wish US implement a similar system but I wonder how its going to work when housing prices are astonomical especially in the Bay Area

Getting paid 250k/yr with 20% downpayment isn't enough to afford a house with 2 kids, so providing a "free" or "afforable" housing to those who aren't currently employees is only going to upset those who are working hard

IMO govn't need to relax the regulation to build more houses and drive the cost down

I completely agree with Finland's approach though. Permanent housing is the minimal requirement to reduce homelessness. Without placed to stay, mailing address, security, it's difficult to get out of homelessness
