Every night for the past year or so, Adriana and Omar Chavez have slept in an RV parked in East Palo Alto, a downtrodden community in Silicon Valley.
On a recent morning before sunrise, they emerged on to the empty street. Omar showed his phone to his wife: 7.07am. “Shall I wake up the girls?” he said, his breath visible in the freezing air.
He headed inside to rouse their three daughters, huddled together in the low-ceilinged bed just above the driver’s cab, and ready them for school.
