The Netherlands and Belgium are popular as a country of residence. No person is illegal, says Bij1. What are the consequences if establishment in the Netherlands and Belgium is legal for everyone?
Population increases by 40 percent due to “no human being is illegal”
According to a Gallup poll, around 700 million people worldwide want to migrate if they had the opportunity. About one percent, seven million, wants to move to the Netherlands. Belgium is less known and smaller. That is why fewer people want to move to Belgium: around two million, seems likely. Seven million new Dutch and two million new Belgians would mean that the population of the Netherlands and Belgium with 40 resp. 20 percent would grow. And the Netherlands is not even the most popular migration country. Switzerland and Singapore's populations would more than double or nearly triple respectively.
No human is illegal? Good news for construction companies and home and landowners
The millions of new residents must first be sheltered. In other words, houses. Lots of houses. Lots of houses. As in: two Brussels, and seven times Rotterdam. The easiest way to achieve this is to build a lot of flats. This way you create many homes on a small surface. A neighborhood with flats such as the L-flat in Zeist (Europe's largest flat) has a population density of around 10,000 people per square kilometer. If you put them together a bit of Hong Kong style. For those seven million extra people in the Netherlands and two million in Belgium, this means a city, consisting of tower blocks, measuring seven by ten kilometers, resp. four by five kilometers, there. In short: a mecca for enterprising real estate investors.
BNP is growing strongly, as is the turnover of supermarkets
The strong growth of GDP is due to this extra alone house building and the extra consumption of these seven, resp. two million people. Of which we will assume that five, resp. three million of age. It is estimated that social services will reach around 100 billion, resp. Pay an extra 30 billion in social assistance benefits and other subsidies, about which later. Much of this will disappear towards the country of origin.
We can assume that they will spend almost all of their disposable income in the Netherlands and Belgium. Social assistance benefits are not very high, namely. From an accounting point of view, this amounts to an increase in GDP of around twenty percent - the shops where they spend their money also have to do their shopping again - the so-called multiplier effect of consumption. Especially the neighboring countries will be happy with this. Their stores in the border region with the Low Countries will generate much more turnover, while they will not have to incur the costs for social services.
Lots of young men, shortage of young women
The group that wants to migrate  consists mainly of young single men between twenty and thirty. That is good news for the voters on Bij1. These are mainly single women. It is less good news for the police and the judiciary. And the male natives, of course. They will have a lot more trouble getting the woman. Or for women who want to walk the streets alone at night. Young men are more likely to be criminals. Mainly single young men. What also does not help is that these men mainly come from African countries. There, women have a low status. The top ten emigration countries are predominantly African.  
More low-educated people who do not speak Dutch
However, employers of companies are happy where many low and intermediate educated to work. Such as gardeners and cleaning companies. The supply of workers is increasing sharply. They no longer need to hire Poland. Highly educated people are less likely to choose the Low Countries. For them, countries with low taxes and high incomes are more popular. Think of Usa and Singapore. If the brain drain is taken into account, the number of highly educated people in Belgium will fall significantly, while in the Netherlands it will increase by 21 percent . Belgium is an attractive migration destination for Congolese and other French-speaking Africans. After all, they already speak French. Even more bad news for Flemish separatists, they are losing their majority. And the Dutch can then come up with new Belgians jokes.
Big debt, end of social system
Someone has to pay these billions. That “someone” is the tax-paying citizen. An uprising will break out if the tax goes up by a quarter. Thus began the 80 Years War. So the government will go into debt. In the first year you have to think of net 70 billion, resp. 40 billion national debt per year. About thirty percent is returned as VAT and other taxes. More in the long run. When more people find work. This means more debt for both countries. That the national debt per year by a sloppy 20 percent, resp. 15 percent per year.
We already have previous experiences with migrants. Many of them will remain unemployed. Seven out of ten Syrian and Somali migrants in the Netherlands are still unemployed . The highly educated will find work faster. The government will probably reduce welfare considerably after a few years. This is the only way to keep it affordable.
"No human being is illegal" and ethnic conflict
Diversity is not always positive. Research data  from Bosnia shows a strong correlation between a mixed population and social unrest. To keep the Low Countries calm, a form of police state will therefore have to be introduced. This ties in seamlessly with the rather totalitarian party program of Bij1 . Among other things, the party wants to transfer control of companies to the employees. Also impose all kinds of extra anti-discrimination rules. Toxic masculinity to punish. And also nationalisations. Then a one-off corona tax on all assets. This only works through a dictatorship.
The richest will leave the country. You are welcome everywhere with money. The rest cannot go away. They have a house. And a job. Also a family. So they will not give up their property without a fight. This is a recipe for anxiety. In short: let's not do this. No human being is illegal, but Lebanon is not a nice prospect.
