After studying what he believes extensively, I'm convinced that in terms of how life would look on the ground level, RFK Jr.'s proposals would definitely cause the biggest changes to society.
His involvement would lead to the mass banning of unsafe consumer products and probably a ton of lawsuits, which would radically change (or kill) entire industries and basically reshape the way most people live and eat.
A lot of products would suddenly look very different without dye. Established brands would be off the shelves and foods people are used to would taste extremely different without chemicals. Children will probably act different as they'd no longer be imbalanced by their diet. Our food supply would shift away from mass production and more towards local supply chains with fresh meat and produce. Removing plastic from our bodies would take the complete restructuring of the way we package things. Microwave meals would be a thing of the past until they figure out how to make it safe. Fast food places would have to close down.
The medical industry would be transformed overnight as the corruption is rooted out and a lot of doctors lose their license to practice medicine. Vaccines would be studied in depth for the first time in history. The unsafe aspects of normalized medical practices would be brought to light leading to a change in the entire industry.
Aside from that, certain industries would be pretty pretty much wiped off the map. Most mainstream pharmaceuticals along with their advertising would be banned. Weight loss drugs would also likely be banned for their links to cancer. Baby powder, plastic water bottles and make up would become things of the past that people look back on in horror. Overall the look and feel of society would be pretty unrecognizable. Less colorful in some ways but definitely more healthy.
I suspect you're right that RFK Jr.'s. influence will be surprisingly strong.
Some things might not change as much as you suggest, however. Women have been wearing makeup roughly forever and in a very wide range of societies. Makeup TOXICITY is a problem, yes, and can be addressed by using less-toxic ingredients. While some women will surely decide to go makeup-free after learning about the toxicity of common makeup brands, I think many more will simply shop more carefully, in the same way that people who learn about the toxins and "empty calories" in many foods begin shopping for healthier choices.
I'm talking about consumer products. I'm sure nothing would stop women from crushing fruits for lipstick and stuff but it would be pretty unavailable for a while.
There are already organic and non-toxic makeup products available; I don't think women will need to make their own, although of course some will do so.
The percentage there is incredibly small compared to the whole industry. 99% of what women wear on a daily basis is toxic.
Well, I suspect you're right about that. As it becomes clear that Trump / RFK Jr. are serious about cleaning this segment up (along with all the others), I believe companies old and new will ramp up creating and producing non-toxic products so that the transition isn't as disruptive as it might be.
