I did the math once and I think it came down to once I've worked a full career at my job I'd have made about a million dollars. So unless you are already old 1 million ain't enough to live off of.Around 40 years of living based off of my income. And i certainly dont want to live into the 60s anyways so eh. Be good enough for me.
I think you'd pretty much need to keep working awhile while playing the stock market to increase that shit for at least a little while.
