Why does much of the Balkans have such a strong emigration culture?

Serbia is one of the shittiest countries to live in rn,only Russia,Ukraine,Moldova and Turkey are worse.Here are the reasons:Corruption is so widespread and normalised that you can,or even must bribe literally everyone,doctors,police,people working in municipality just to do their work and corruption in the goverment is WILD,they even publicly admitted that there is massive corruption but people are so used to it so they choose to ignore it.By corruption perception index,Serbia has same score as Ukraine which is basically in a full scale war.Groceries cost same as in Germany,salaries are among the lowest in Europe, official data provided by Serbian bureau of statistisc says that median salary in Serbia is 730€,basically meaning that half of country is making less than 730€ net per month.Housing prices to income ratio are according to site Numbeo are the worst in whole Europe, its literally impossible to buy property for people who work for average wage,even if they make a lot above the average ,they still need a massive and probably life- lasting loan from bank and loans have one of the highest interest rates in Europe.Our prominent mafia members and criminals are guared by police,there is a tent settlement in front of national assembly full of criminals and its functionating as a state within a state,guarded by police and no one can enter there without their permission.Some journalist who tried got their cameras broken by criminals or they even got beated up by criminalsinside,but police has an order not to react inside of that "settlement",which is illegal of course,but its Serbia so who cares about what law says.Anyways,to put is short,unempleyment is on the rise,many companies closed their factories in Serbia in last few month,democracy is long gone and we are living in open autocracy,criminals who have close ties with rulling party can literally kill you if they wanted to with very low to none legal consequeinces and im not exaggerating,we are also a Russian puppet state who is facing severe consequences because of that,first one being our national oil company being sanctioned by USA and fuel shortages are pretty much possible in a country in the middle of Europe-in 2025.You are highy unlikely to get a normal job outside of two largest cities because of huge centralisation,and for people outside of them there are only two possibilities-either to move to Belgrade or Novi Sad,or to became a member of the rulling party in order to get some shitty job in their town.Air pollition is worst in Europe,majority of county is from november to april constsanly exposed to extreme air pollution and no one gives a shit about that.And yeah,the most important reason,a train station canopy in Novi Sad failed last year and killed 16 people below it because of corruption linked to goverment officials and even our authorian president itself,and court in Novi Sad ruled out indictment against government officials who publicly said that the station is 100% safe and ready to operate,and by that court wants to say that no one is guilty and that it didnt kill enough people to be considered as a serious crime against public safety (yes,the judge seriously wrote that in official explanation).Serbia right now is hell on earth,and majority of people under 40 wants to emigrate.
