They are able to cure basically anything. And yet, they allow millions of Muggles (including children) to die painfully of cancer and other nasty diseases.

They are able to cure basically anything. And yet, they allow millions of Muggles (including children) to die painfully of cancer and other nasty diseases.
Why?
This is directly addressed in the opening of Harry Potter and the Philosopher's Stone.
“But what does a Ministry of Magic do?”
“Well, their main job is to keep it from the Muggles that there’s still witches an’ wizards up an’ down the country.”
“Why?”
“Why? Blimey, Harry, everyone’d be wantin’ magic solutions to their problems. Nah, we’re best left alone.”
So yes, it would appear that the wizarding world is callously indifferent to the plight of Muggles or at least recognises that if they provide magical help, it might expose their world and make them into a resource to be exploited.
