Tipping Point Community CEO Daniel Lurie talks with Recode's Kara Swisher about his organization's efforts to fight homelessness in San Francisco. He says it's all too easy to "not see" the incredible poverty and inequality in the Bay Area if you commute into Silicon Valley every day, which means people in tech must be educated about the problem if they're going to be part of the solution. Lurie calls on techies of means, the beneficiaries of "this incredible moment in time," to get involved in philanthropy. He argues that civic involvement won't last if it's mandated from the outside, and that companies must see it as a cultural priority, with the energy to help coming from the top of the org chart.
