In the US at least, the dismantling of the public health systems in the name of efficiency is something that occurred in several previous administrations of both parties, backed by a public who supported those cuts in order to receive greater investment returns and lower taxes.
Furthermore in what way was the US public health system dismantled? The US was best suited to take on Coronavirus because of its significant number of ICU beds and the number of ventilators compared to the rest of the West. The unfortunate fact is that CDC's tests failed and that left the US flat-footed when it was otherwise better positioned to tackle the crisis than most.
