What kind of country do we want to be?
Do we want people begging in the streets to feed their children?
Do we want people sleeping in the streets?
Do we want people wandering among us carrying infectious disease?
Do we want people dying in the streets?
That is how third world countries operate. There is no "safety net" in third world countries. You live or die based on your lot in life.
We are the wealtiest country on earth. How do we want to be known based on our treatment of citizens?
Shouldn't we strive for the best?
All of those are incredibly ambiguous, general, vagueries. 'Shouldn't we strive for the best'? The best what? Best at giving people as much as humanly possible? Best at making sure everyone's needs are taken care of? That won't create the 'best' society by any stretch of the imagination.
You're 'Do we want' list implies that those things would happen if someone else didn't do them for them. You don't live and die based on your lot in life. You live or die by the strength of your motivation or lack of it.
When you list all these doomsday notions about what you think will be if we don't provide all these things you do other things as well. You lower expectations for society as whole. Don't worry we don't expect you to feed yourself. We don't expect you to actually pay for your house. etc.
When it is understood that certain things are not expected of you, in most cases, you're not going to do them. You are going to DO less. You will be challenged less and as a result you will become weaker. Is that really what's best for society?
