The big Thrive-no!

Corey hits $$ use

Mayor de Blasio and First Lady Chirlane McCray’s signature mental-health plan, ThriveNYC, must use the lion’s share of its massive $1 billion budget to actually help those who need it most — people in crisis, City Council Speaker Corey Johnson insisted Tuesday.

“I have concerns that we need to be doing more for people with serious mental illness. That’s what we need to focus the money on,” Johnson said Tuesday on Fox 5’s “Good Day New York.”

The embattled program largely focuses on preventative measures and programs for people with depression and anxiety.

Only 12 percent of the $1 billion plan goes to people in crisis, according to DJ Jaffe, director of the Mental Illness Policy Org.

That needs to change, according to Johnson.

“We need to be putting that money into people that people see decompensating on the subway and on the streets of New York City, who don’t know who they are, who can’t get the help they need,” Johnson said. “That’s where we need to funnel that money.”

Jaffe and other critics have long argued that more ThriveNYC funding should go toward preventing homelessness as well as the arrest and incarceration of mentally ill New Yorkers.

“Right now, Rikers is the largest psychiatric facility in the United States of America,” Johnson said, referring to the city’s largest jail.

“A significant amount of people there have serious mental illness. We need permanent housing, transitional housing.

“You would keep a lot of people out of the system,” Johnson concluded.
