ELI5:What is the difference between "Obamacare" and universal healthcare in other countries, such as the Canadian system or the UK's NHS?

I know that Obamacare is sort of a compromise, and that it's not really government healthcare, but I just don't get it.  I've searched ELI5 and read some of the ones about Obamacare, but I'd like to see sort of a comparison between OC and government healthcare.  ELI5, please?

It's really really different.

Obamacare is really a term to refer to the law which increases government involvement in healthcare and adds additional regulations on health insurance companies.

If we were to implement a healthcare system like in Canada or the UK we'd have started providing healthcare directly through taxpayers (in effect the government would be the "single payer") and the government would run the healthcare system as a whole.

As it stands The changes in obamacare are far closer to what we had before it, then to systems like in Canada and the UK.
