The thing about our current economic implementation is that, while it's not the best we'll ever have, it's simply the best way we've come up with for doing things, and it does a decent (not great) job. You need to provide something to society to justify it providing something to you. We will eventually come up with a better way of doing that, this cycle of pooling wealth outside of general society cannot continue. Certain elements are reaping far more than they provide, with damaging long term implications.
My question to the "entitlement" camp is this, where do you draw the baseline? How many kids are you allowed to have before we make you start doing something to support them? How much medical care are you entitled to before you have to start paying for it? why
with billions of people starving in the world should you
be guaranteed a comfortable existence simply because you did well in the birth lottery? We can do better for ourselves, but it won't be done by mortgaging society to provide for those who do not contribute.
Also, I think a lot of us underestimate the laziness of people.
