in the open petition it is not mentioned what is exactly meant by " an adequately funded package ", but I think a moderate possibility is a plan that allows artist shift their focus partly to the current needs of the society and serve the society on what is more needed in the time of crisis and partly stay producing their art. This could be possible by investing on a diverse shortterm education plan designed to learn the new skills needed to serve the new needs of the society in the time of crisis! but also providing new possibilities that people could enjoy their art.
