When OMB head Russ Vought talks about deliberate efforts to put federal employees "in trauma" and make them quit their jobs, he's talking about people like Michelle, recently fired by Musk/Trump. www.sfgate.com/california/a...
Michelle Beutler cleared 67 trees off a U.S. Forest Service road in two days. It was the spring of 2023, after a record-breaking winter in the Stanislaus National Forest in California’s Sierra Nevada. Beutler, 59, worked alone with a chain saw to remove every fallen tree on a 10-mile stretch of road between the town of Long Barn in Tuolumne County and the popular Hull Creek Campground. She single-handedly finished the work so the road could open in time for Memorial Day.

As a recreation technician based out of the Summit Ranger Station in the Stanislaus National Forest, Beutler’s job was to clean toilets, pick up trash and maintain recreation sites and campgrounds up and down Sonora Pass. She’d typically drive her Forest Service truck 100 miles a day. She sprayed pit toilets with a fire hose. She wiped away graffiti and removed thousands of pounds of house trash, old furniture and useless stuff that people dumped in the forest. She extinguished hundreds of abandoned and illegal campfires. She assisted law enforcement during emergency accidents, helping officers navigate a swath of rugged forest land that she grew up on and knows intimately.

@elonmusk
We spent the weekend feeding USAID into the wood chipper. 

Could gone to some great parties.

Did that instead.U.S. policy was to help bring an end to apartheid and establish a nonracial, democratic government. In response to this policy and the Act, USAID/South Africa was responsible for financing projects that apartheid victims viewed as critical in promoting social, political, and economic change through peaceful means.

The mission enabled community consultation and ensured that the United States did not impose foreign-defined solutions to local problems. USAID created projects and activities to respond to the priorities of the black community and its leaders, maximized black participation and leadership, and ensured activities had a linkage to the general objectives of U.S. policy.

First-year funding for the program was $25 million, which was raised to $50 million the second year. The main project areas were community outreach and leadership development to redress the repression of black-led institutions; educational support and training to address the educational crisis in South Africa; black private enterprise development to combat the inhibiting effects of apartheid–induced discrimination in private enterprise; university grants to help create a new generation of economic and political leaders; human rights; legal assistance; labor union training; and health and nutrition

Controversial opinion (or not): the global burden of diseases is like nuggets, which are based on chicken. GBD is based on real data but it is not real data. Like ultra-processed food, it sells a lot and tastes good, if you do not have chicken, you go for nuggets. Do you agree?
