Why should I solve your problems for you?
If I spend my own time and money building a homeless shelter and making sure every homeless person in town can get a basic meal and the health care they need then you don't have to worry about
being bothered by homeless people begging you for money or stealing when they can't get what they need by begging.
You've benefitted from my solution every bit as much as I have. Why shouldn't you be required to chip in?
What if I decide to build a road for me and my neighbors to use? It boils down to being your choice and that is the point. You want something done do it.
I had the public road to my my house paved and marked, it was supposedly gravel, more like badly maintained dirt road. Others use it the county is supposed to maintain it, but I put it in and maintain it to MY standards even though technically its a public road. It's not closed off and my neighbors all use it. I have never asked them to pay for or maintain it.
I put the road in, because it snows here and I have heavy equipment that comes to my property so I wanted the road from the state highway to my home be capable of handling that kind of load, for safety reasons, and be easy to salt and plow, which I do myself on occasion. I also had new solar powered led street lights installed. Because I payed for them, I picked the design I liked.
You know what happened after I had the road installed? Some (most) of my neighbors came to me and wanted to pitch in on the maintenance, and some even wanted to help allay the cost of the road. I declined the help for paying for the road as I got a tax deduction for it as a business expense. (Very nice deduction.) I do however accept whatever my neighbors wish to pay into a formal maintenance trust fund, the ones able are very generous and the ones not able, have volunteered to plow the road if I lend them my equipment. (They are on a rotation where there are enough volunteers, nobody has to plow very much, works well for me and them.) County is annoyed at me, but that's their problem. ( I put a sign up saying who paid for the road while it was being built, just like they do for the roads they do. Also I didn't ask them.
) The road coincidentally improved everyone's property values.
I also provide free education to all my associates (I hate the word employee.) children, so they get a superior education and not have to go to government halls of indoctrination. Their families get to see their kids during the day and the kids do and see things they wouldn't ordinarily. I don't ask for a dime yet all of my associates help contribute in whatever ways they see fit. My customers have remarked very positively about the atmosphere of the company because the children are there doing and learning important things about life and work and interacting with adults. I have retired employees who come in just for seeing, and helping teach the children their skills. One my best policies I have ever done. It benefits everyone in my business.
I don't do charity. I do things that benefit others and myself, and I expect nothing in return. That's how you make the world a little bit better place, by doing things of your own accord according to your means. I am pretty well off so I can do more of what I want, others who are not as well off do what they can, until they get to a point where they to can do larger things. It's not rocket science. Its basic leadership.
