Congratulations and good for you, but you're one of millions. I grew up poor after my father died when I was eleven, and while I didn't retire a multi-millionaire, I'm happy and quite comfortable with where I ended up in my retirement.
In 1980, when Ronald Reagan was elected, you had a 20% chance of working your way out of poverty. Thanks to Republican economic policies, today, a child born into poverty has a 2% chance of doing what you accomplished. If you had grown up in the 80's, you'd still be working for slave wages, and/or paying off college debt.
