If there were one food & safety item the Biden Administration should put its focus on, it's destroying the US addiction to sugar generally and high fructose corn syrup specifically. It would be an immense contribution to roll that backwards. And fix the mistake of proclaiming fat in general to be the problem decades past, by pushing national education on healthy / unhealthy fats. The US Government has a budget to put ads everywhere just focused on this matter.

And regarding the healthcare industrial complex. For the US scenario, there is only one approach that will work at this point: California needs to build its own universal healthcare system from the ground-up, and that includes utilizing the UC university system to train / educate its labor just to build that up. It's already understood how to model it, there are numerous good example nations to choose from (there are obviously multiple variations of a universal system that will work, and far better than what the US is doing now). California has scale and can control many aspects of a healthcare system that a smaller, weaker state can't (including manufacturing its own generic drugs if necessary).

Many prominent politicians keep trying to force universal healthcare as an idea, as though we can just slap it on top of our existing cost structure. It doesn't work right now due to the extreme cost of US healthcare (unless we want to instantly go broke nationally). You have to be able to start over from first steps and contain the cost correctly from day one. California is one of the few places that can do that, and it has the best shot at it overall (some money, majority favors universal healthcare politically, UC system, etc).
