Denver Public Schools:

"Stay enrolled in your school! For every student who unenrolls, the district loses approximately $10,600."

They're worried families will find alternatives that actually open this fall.

Yes they used the exclamation point

The school district also discouraged pandemic pods because of "equity implications"

The school district also said "please do not hire Denver Public School teachers"

They're discouraging families from giving teachers opportunities to make extra money.

They say they're concerned about equity but then say families should:

"Reject the notion of school vouchers and stipends that further siphon funds from public education."

But that would allow less advantaged families to access alternatives as well.

Imagine if someone said "using your food stamps at Trader Joe's siphons away money from Walmart!"

That would be ridiculous

The money doesn't belong to the institution

Education dollars are meant for the education of the child - not protecting a government monopoly.
