I mean i think It's possible to stop working on 100k depending on your goals and how aggressive you are. If you ask me, Real Estate is your best bet, but I don't know a lot about investing.
-$100,000 after taxes is about $6000/month here in Illinois.
-Live off $2500 and have $3500/month left over.
-You'll be saving $42,000 a year. 2 years you'll be at $84,000.
That $84,000 can go towards a multi family home worth $400,000(20% down payment) in a good area. I say $400,000 because in most areas that's a nice building that doesn't need rehab. So you got a $400,000 4 unit multifamily home. Mortgage + Property taxes would probably be $2700, but with 4 units you can get $4000. And from there you just build up. Either take that $1300 profit and put it towards the mortgage or stack it up and buy another multifamily home. But if you pay off that property early, that's like $3000(-$1000 Taxes) in your pockets. So now you got $6500/month going in your bank.
This is just off the top of my head

$100k salary may not be a lot to y'all but it looks like it can really get you places.
