Let's compare two examples to those who are new in Finland and follow different paths in their life as immigrants, where one continues to work while the other pursues the path of integration and education. Specifically let's name X - the person who started working and Y - the person who followed the integration path.
If a newcomer to Finland starts to work, of course it is a positive thing, but on the other hand, the impacts can be seen in a few years. Taking into account several factors such as language, new environment and professional qualifications, the salary of newly employed X person can be brought to a low level, as example 10 € / h.
The person in question with the initial salary will end up with a minimum standard wage and thus in many cases to reach the proper level of expenses and other family needs, it is obliged from 8 hours to work additional hours 10 hours a day and also from standards 5 days a week sometimes he is forced to work 6 days to earn a sufficient salary.
Continuing work in this way to X person in a several years can only increase the salary for few euros, as an example after 10 years he can earn something around 12-14 € / h but this will not be enough to cover the average cost of living, saving and thus the opportunity to continue working with additional time will remain an open option.
We go to Y person who has begun to follow the path of integration and education. If we compare, the income of a student or someone attending vocational education, are smaller and in this case let's he gets 7 € / h, so the average income significantly affects compared to the X person.
Y person will continue the path of integration and education and after some years the income is still much smaller, but on the other hand he has gained a profession that sees a better future in terms of work and if he is employed in an enterprise certainly not at first will benefit so much but at least will reach the X person's salary as example after 3-5 years engagement in integration and education issues, the Y person's income matches the income of Person X at 10 € / h.
If a Y person starts working or continues to go further to school, whatever he is doing, he will start to have better incomes and is easier to cover the expesnes with an average salary, therefore the need to work extra time is lower.
The examples above were just an illustration or an opinion from my many years of experience with integration issues and things show that the more we integrate, the easier we will have the life we are living and the less assimilated we will be therefore advising you that integration should be of special importance.
