Being a quasi-"respected elder" myself,  I wholeheartedly support a return to a small income tax to help us start paying our own way – and seniors who can't afford it should contribute just as much as anyone else. 
The income tax proposed is only 3 or 4% of  ones taxable income -  less than we used to pay, and not very much for the opportunity to live  and work in the most beautiful and most generous, state in the union – with more opportunities for individuals to be entrepreneurs or to choose a lifestyle  of freedom and expiration than any other state in the union. A little gratitude and a little " ponying up " for all our blessings up here seems in order to me!  And an income tax it takes more from the 1%-era and Lowe 48-era working here then it does from a single Alaska  mom of little kids seems eminently fair to me too!
