Saving $10k/year is $833.3/month going in to savings (so $1600 left to live with). Doable if your rent is cheap.
Sharing a 2br is even cheaper. And this is only if one wants to buy a house all-cash.

While the forklift driver is slowly saving 10k a year for a 150k house, the SF bro is saving 50k a year for a similar house for $1M. Guess who gets to the target first.
