So if you argument is that we should increase taxes so another Mao doesn't exist, I'd rather just kill Mao.
You might not be sympathetic to your fellow animals, but you can bet that if a bunch of them frightened, angry, and hungry start circling because they see you as all that stands between them and survival they won't be very sympathetic to you either.
We already make a number of concessions to preserve a polite society. Keeping your fellow animals fed and making sure they have a chance to advance (something to work for) is a small price for security and stability because otherwise those things are impossible.
You can think of it as ransom, but I prefer to think of it as an investment in and routine maintenance of society itself and ultimately we all benefit and see returns on that investment.
You're probably right to not be afraid, but things can kick off when the circumstances are right for it. And we haven't arrived at this historical moment by being nice.
The fact is, however, that modern society doesn't fit everyone. Since we won't allow people to withdraw from society that means we're actively forcing people to live a specific way of life that some simply cannot handle.
Simply putting more pressure on those groups will result in the forming of parallel societies and in the long run that means that those parallel societies will form a separate culture and try to secede. If we stop that there will be conflict. History tells us such conflict will be very bloody, no matter who ends up on top.
This is a cycle that Western Civilization has dealt with for thousands of years. Personally, I wouldn't mind trying to break it this time.
Sometimes (although far less often than some people would like to assume) the person who withdraws is perfectly capable of handling the demands we force on people in our society, but they simply prefer to not participate. These people usually aren't sitting around all day collecting welfare checks, often they are the career homeless or living in isolated shacks in mountains. I can't really fault them if that kind of lifestyle is actually preferable to them.
We shouldn't assume it applies to anyone just because it applies to some indivuduals though.
Those rabid unproductive people are rabid and unproductive because society can't provide basic necessities such as 'housing' or 'food' or 'water'. They are being made rabid by people that would deny them the basics needed to survive.
Your argument is essentially 'Let them eat cake' and if you're at all familiar with history, I need not mention the possible origin of that phrase. When you create a desperate class of people willing to do anything to survive, you shouldn't be surprised when they show up at your doorstep seeking to drag you out into the streets.
Here's one to get you started: When a very small number of people have everything and a great many people have nothing, not even what they need to survive, those hungry desperate masses will have nothing to lose and every incentive to take what they need by using any and all means.
Next, try to think about what might be potentially lost when large numbers of people are needlessly dying. What contributions great or modest those lives might have made if they'd been able to survive.
I'm not suggesting you should be personally responsible for providing for every person's basic needs, but it doesn't take a great amount of creativity or insight to come up with pragmatic reasons why we might be better off collectively if we work collectively to minimize the number of people around us who are struggling with the basic necessities of life and well-being.
