I was born in the US but have lived in the UK since 1995. I don't understand why everyone hates Obama's healthcare either. I think there should be universal healthcare, and a lot of my friends do - but then I see that we have emigrated.
My family was poor. We couldn't afford to go to the doctor or the dentist - I finally saw a dentist at age 11 & even though we didn't eat sugary food, etc I still had cavities that needed treatment and two rows of teeth (my baby teeth didn't fall out by themselves) that my mother begged the dentist to pull out while I was numbed up for the cavity work. Thank goodness I didn't need glasses back then!
When I was 19 I suddenly started bleeding copiously. I had no idea what to do, because I couldn't afford treatment. Long story short, I was diagnosed with Ulcerative Colitis at age 19. I didn't drink or smoke, I didn't engage in any risky behaviour to get this serious condition. Yet, when I try and explain all this to my family I get the "oh, you want Socialism?" comments.... and lots of ranting about how they don't want to pay for smokers' problems, or alcoholics' problems or people like me, presumably.
And yes, lots of Americans hate the NHS or what they think the NHS is, because naturally they've never travelled to the UK or actually experienced the NHS. I always sing its praises, how I have a good quaility of life here, and was constantly ill in the US because I could not afford to see a doctor, or gasp a specialist, about my medical condition. The prescription I take costs 10 times as much in the US, for example. I suspect my life expectancy, had I stayed in the US, would have been seriously shortened.
I don't understand it, but then, there are many reasons I chose to leave! I guess if I understood hating "Obamacare" I'd still live there....
