Maybe in some magical AGI future computers can do the work, but until then where else is the effort going to come from? It isn't going to randomly appear out of thin air, that is for sure. There is nothing else to "blame" but them.
It's not the "corporations"[1] keeping you from that six pack, nor it is it keeping you from building a single payer healthcare system. Not wanting to put in the toil to make it happen will certainly get in the way, though. We all understand why nobody really wants to put in the hard work and suffering to make the necessary changes, but that doesn't change the fact that it won't happen until you do it.
[1] Which, in this context, is just another way to say people. And in this case often the very same people. ~40% of US corporate stock is held by Average Joe retirements savings account (IRA, 401k, etc.). Ask these people if they'd like a single payer healthcare system and the answer would almost certainly be "Yes!". But if you then ask them to do the work to see it through: "Never mind. What we have will do.".
