General Discussion

Did you even stop to think about what you were going to say?
I don't know what happened to you, you used to actually use your brain.
Let's slap you upside the head with the universal reality check clue x 4 and knock some of your unused brain cells together and attempt to get them working again.
Reality for many seniors: They get laid off from companies that don't want to pay retirement. Many also have major health issues that need medical care. Seniors have already devoted much of their life to working, often at jobs that never went much above minimum wage. Many seniors don't even consider retiring until age 62, some age 65, if their companies don't have a mandatory retirement age.
So no, seniors won't contribute much more to the gdp than they already are.
Here's a better suggestion- let's tax the crap out of those who make 100 million or more a year, close all the tax loopholes that let them get away with contributing nothing, but taking everything.
