I am 71. We don't need people of my generation running in 2020.

135. I agree with you and I am twice your age.

A good leader is hard to find. If you find a good one you don't discount them because of their age. Might as well discount everyone before you start if you are not going to latch onto a good one. Let me address what I see in your issues mentioned.
Higher wages - A livable wage now - a guaranteed income for all. Progressive taxation that will eliminate income inequality or at least move the problem in the opposite direction.
Student loan debt - It should be with no interest like they do in Australia. We should have quantitative easing for people and not banks where we buy up the bad debt of people in unfortunate situations - This includes student loans- bad universities, deaths, depressed areas where there are no jobs.
Social security - we should double the amount and or have a minimum guaranteed income.
Climate change - declare an emergency now and try to cool the arctic and stop / remove carbon dioxide and methane. 100% phase out of carbon based energy
Any candidate seriously promoting any or many of these would be a good leader.
