Let’s take the ACA. That was designed to fix the problem “healthcare in the US is insanely expensive and insurance companies can deny coverage if you have a pre-existing condition.” How could you fix that problem individually?
My argument there wasn't actually that all of those could have done bottom up, only that they are examples of us granting the government more power and asking for a collectivist solution. That isn't always a bad thing, but it does point to the trend that I recognize (potentially due to my bias as pointed out above).
Personally I think the US going from extremely hyper-individualistic to the point of self-destruction to slightly less hyper-individualistic is not a sign of a shift, but rather a return to normalcy.
We forget that the US has been far, far more collectivist in the past, particularly from the 20's - last 70's. The shift towards hyper-individualism is, in my opinion, a wealth extraction mechanism masquerading as a strength. It is highly beneficial to every wealthy person to have low regulations and low requirements for care. The ACA is just common sense - the reason we didn't have it isn't because of individualism, but rather because by not having it you can make a lot more evil and consequently make a lot more money as an insurer.
