Why do you have to shake the number when buying a house or a car?
If you don't shake the number, the good license plate number will be bought by the rich. If you have money, you can buy anything. They can spend more money to buy a good license plate number, which is unfair to many ordinary people.
Fairness can only be expressed by drawing lots. You don't know the number before the lottery, and you can't decide whether you have money or not. If you buy all the good license plates, it will cause rebellious psychology, and even many people choose not to buy a car, which will be considered unfair.
So is the house. I bought all the good levels, but I can't sell all the bad levels, or even sell them. Therefore, buying a house depends entirely on luck. Lucky people can choose a good level.
Those who are unlucky and choose a good level will not blame the developers, but only their own luck. You don't have to buy it if you don't want it.
The lottery is just to calm everyone's hearts and let the masses know that everything is fair. If it is unfair, maybe many developers are crowded with petitioners at the door now, just to convince you that you don't need anyone.
Of course, in addition to the lottery, if you want to get a good license plate number or floor, you can spend money to go through the back door, not directly participate in the computer lottery, and let the staff give you a number directly, which also depends on your ability. If you can, that's the best. If it doesn't matter, let's draw lots honestly.
