From what I understand, he’s mainly concerned about the possible revocation of the “pre-existing conditions” requirements of the ACA.
My own family’s move to the USA from the UK was only possible thanks to Obamacare; I have pre-existing medical conditions that made me uninsurable as a freelance writer, small business owner and novelist, and any move to the USA without some way to get healthcare would have put my whole family’s finances – from our home to our retirement to our daughter’s college savings – at risk (I’m pinning my hopes on California making good on its promise to lead the resistance to Trumpism, including the extension of a state healthcare plan that could even include single-payer healthcare or a public option).
