Philanthropist of Knowledge and Skills

So how does one become a Philanthropist of Knowledge and Skills when one is Financially Handicapped?
In the words of Yul Brenner from The King and I "Tis a puzzlement".
I am going to start researching. There has to be a way for people to share their knowledge and skills for the betterment of this country.  Even if they are Financially Handicapped (or broke).  These people many times have skills and knowledge because they have had to make do or did it as a job.    Retired people are another source of knowledge and skills; and many of them can't afford to go out a give.
It takes time, materials and gas to teach and share skills.
It also takes pupils, to many people in this country are lazy or skeptical.  They wonder just why they need to learn a particular skill or knowledge.  We aren't growing as a country.  I have said before we need to produce in this country, knowledge and skill as well as goods.
We need to share skills to improve our family's lives, as well as the lives of other.  We need to share knowledge the will help us make inform choices.  People have lost the ability to help themselves or their family.  They hire someone (now mind you there are tons of people who need employment) but what happens when you don't have the money to hire someone.  We have lost a sense of community in this country.  We don't help our neighbors, hell alot of people don't even know their neighbors.  Oops another topic, brain just starts going every where.
We need to join together as a human race and teach and help one another.  But again it will come back to how do we support such things, when we are struggling to survive ourselves!
