No thanks, can't see anything good coming from that (...kind of ideas, and comparing different countries with mostly capitalist economies with varying levels of a) market regulation, and b) socialized public institutions/services, it seems to me that the less a country has and does either one of the two the worse that country fares on:
* healthcare accessibility and quality on average (and the price of it - I don't get why even selfish sociopath, in fact especially such person, would want to pay more for healthcare to make sure his healthcare spending isn't going for anyone else but his healthcare).
* safety from a) criminal activity and b) police brutality
* general level of education
* general feeling of content, satisfaction and happiness on average
* etc. etc.
I know that's a gross oversimplification, but whether one disagrees or agrees with it the act of pretending not understanding what I mean and acting like I meant something else just makes a person seem dumb, so please for your own sake everyone, consider not doing so (I know it's the long lasting trend on internet).
Also, while it may seem at first that those on the top of the material wealth pyramid might be able to nullify any and all such effects to their own life, I don't think even that is really true anyway - all their money is at least good for keeping them from seeing what they are missing out on. Just like the loved leader (pun intended) of North Korea, I'm sure his feeling like king of the world and he don't really have to worry about not affording something, but really I'm sure that anyone can see how much of stuff that actually matters he must be missing out on when compared to any average upper middle-class citizen in Europe, US or Japan (for example).
And I don't think all the time I've spent on writing all this here is worth it, for whose opinion is it going to change?
Still, I rather not go with the dog-eat-dog kind of system you're proposing and rather go with system where everyone is expected to chip in for the general good of the people, as it's compatible with natural human behavior - I do believe it's not only more ethical, but in general it's results are better for upper as well as lower classes, business owners as well as working class, everyone except maybe the 1% and even for those the only way it's not better for them is money wise, which really doesn't matter for them unless they insist on sticking with the mental delusion that the amount of unnecessary money and power is worth anything.
