Unless you live in a hut in Thailand or something.
Even when you're young and single, it behooves you to think about retirement; it's sooner than you think.
You need a safety net in case something happens, leaving you unable to work for a long time.
If you support a family, you have to think about things like education funds for the kids, and what happens if you suddenly die.
Retirement is provided by the state here so it’s not something I have to plan for.
Again, just to reiterate, the original post was using 2k/mo as the absolute minimum and the point I was trying to make is that a few Ks a month is a reasonable living in way more places that people realize.
But I suspect a non negligible % of people here on HN have a distorted view of the world and how much living cost.
[1]: Typical supermarket job in Austria: https://jobs.aldi-hofer.com/hofer-karriere-at/job/Linz-BACKB... The advertised salary for 21 hours/week of 1330€ is paid 14 times per year and comes to a total income of ~15.7k€ after taxes. If you make 24k€ a year as a self-employed person, you will have to pay ~400€ taxes + 6.5k€ pension + health insurance leaving a total of ~17k€ after taxes.
If you have irregular income, you need to plan for a lot more since you'll always have slow months with no income, or customers that don't pay or pay much later than you expected, and you have a lot of costs that employees don't (eg. you need to pay for your own hardware, office space, accountant, tax advisor, health care, pensions, unemployment insurance, etc).
I'd really love to hear from someone who is making a living from bounties or hackathons, because it just seems very hard or impossible to me.
You probably won't get rich from doing $500 bug bounties.
But there are hackathons with bounties in the $1000-$10000 range.
Do 2-4 of those per month and you're good.
