On what grounds do you conclude that gambling is currently attracting children? I am in contact with a lot of people and I have never heard any of them say that their child has a gambling problem. There are problems with some children being addicted to donating to various computer games, some are seen using vapes, but no one has ever told me that any of their children are addicted to sports betting, dice or slots.
This is easy to address, if the game is reaching children, it is not the children's responsibility, it is the parents' responsibility, because if children enter the games it is because the lack of parental supervision is evident and the fault is with them, for children there should not be any entry into a casino, there should not be such access because the first ones who should block such access are the parents, parents should be much faster than the internet in that case.
