Talking about Brazil and my reality here. I`m 24 and I still live with my parents and depend on them for basically everything, I still even get a montlhy allowance so I don`t have to ask money for everything. And it`s actually pretty ok and common around here. My college friends, in Law School, that are in the same age group as me mostly have a life like mine, living with parents and acting. The early twenties actually are some kind of extended teenhood for me and many friends of mine.

I`m going graduate next year, and look for a job and etc., but either way I won't move from my parents house because my budget wouldn`t allow me to keep even half of my living standard, and instead I`m going to work to save money to travel to Europe in early 2018 and hangout a little more. 

The situation I just described is the reallity of most middle class and upper middle class young adults in Brazil, staying as much as possible with the parents so we don`t have to face a plummeting of living standard.

I want to here from you, I know that in many countries like USA and France the situation I just described would be considered absurd.

I am in the US and I lived with my parents until I was 23, but I was far from dependent on them in the way you describe. I paid half the bills, I made my own money, I managed my own credit, etc. That said, my friends still thought it was weird that I lived with them for that long.

Its less about culture but more living area. Where I live, it is impossible to live without roommates unless your wealthy , so younger adults tend to live with parents much than you young adults in, say Kansas. That allowance thing though, you are waaaaay to old for that.

In the US moved out when I was 20 many years ago.

I live in Finland, and it's very common to move out as soon as possible, which is often after graduating from secondary education (i.e. upper secondary school or vocational school). That's roughly at the age of 18. Of course there's some variance to this, and some move out earlier, some later. I'm not entirely sure about social acceptance regarding living with your parents, but I think it's thought unconventional and possible looked at a bit oddly if you're living with your parents much longer than what's typical. For example, living with your parents at the age of 25 would probably be considered a bit odd. At 30, you'd probably be considered a loser unless you had a really good reason for living with your parents.

Here is where cultural differences surfaces. Here it`s actually very ok, sure, it`s not ideal, but isn`t something that just I receive for example. Kids around here for example that go to medicine school, since it`s virtually impossible to have a job and study medicine, they get allowances from their parents till late 20`s easily. 

And for example, my allowance is around 2x the minimum wage. I don`t want to enter in this discussion in depth, but it`s common in upper middle class for people to receive allowances from parents. I know people in their 30`s that still receive money from the parents.

Well, maybe you should be more specific. Im 31, but I havent bought a house yet. I think thatll be next year. Still living with my parents.But I have been paying my own bills/food/games when I got my engineering degree. If it were up to them, they will like it for me to stay more, but I want my house, and to get married soon.

But this is what I see. Upper classes in poorer countries people tend to depend on their parents for longer than for example young adults in 1st world countries like Finland. I mean, how much a brazillian 18 year old would make whitout college level? Around 1000 BRL if he`s lucky and working 44h per week. That`s plan poverty, or at least would be considered so in a 1st world country. 

Yeah, there's definitely differences between rich and poor countries, and for a good reason. We have good social security programs so everyone can live on their own (pretty much), but I don't think that's the case in poorer countries (or even in all rich countries). Thus it makes sense to live with your parents in poor countries, and I think it makes sense even in rich countries. It's just that people become so independent so young here, so they move out even though it might not make the most sense. I was pretty eager to move out myself when it happened, because it could be pretty annoying at times. So much freedom when you're living by yourself (or with a flatmate...)!

I'm from a similar culture as you (Venezuelan), and it's almost the same deal. I'm living in Canada with my sister, and we both are making money, but we still heavily depend on our parents. And, I don't like saying it, we are pretty wealthy. Out of our friends (mine or my sister's), we are the best off. I guess we don't depend on them as much as our friends. And we wouldn't consider any of them as losers or any of that.

My sister is 22, I'm 18. I could see us depending on them for a few more years (more for me). But my friends back home? I can see them living with their parents until their late 20s.
