From children's perspective, I think this may solve some realistic problems in the short term, but in the long run, this will damage the creativity and motivation to face life challenges and harm the ability to manage finances, especially if you are a man. I say this because a lot of the friends from my generation are struggling financially now because they have been dependent on their parents and even after getting married and establishing a new family, they took a regular amount of money from their parents to pay off mortgages or cover other expenses. They've never thought about having another stream of income or one day their parents may not be making money and instead need money and care from them. A lof of hidden problems are there but just ignored. In my opinion, the earlier you become independent financially, the more likely you will be living a comfortable life with your finances. Better to know this and be prepared, if you are young.
There are a lot of people who were born in poor families but have zero motivation to escape the poverty. When I see people like Cristiano Ronaldo and Conor McGregor, I always think that you are either born with it or not. These are the people who were chasing money and luxury life because they were poor and couldn't afford what they wanted. When you chase it, when you fight for it, when you have right mentality for it, then you do whatever dream your mind can imagine.
The reason behind why I mention these two people is that to my mind, Cristiano Ronaldo isn't talented footballer (Messi is a true talent), but instead, he is a very dedicated and hard worker person, this is what made him successful, his mindset, his dedication and willpower.
And Conor McGregor, while is acts a bit cocky, it's true that he earned himself his fame, money, everything. He made UFC more famous and interesting. While he certainly is not the best fighter, he is the best seller of the show, the highest-paid athlete in UFC. He made it, he made others to earn money too.
When it comes to family, I don't think that help from family makes you poor. Well, if you are from rich family, then this can make your more unmotivated but if you come from average family, I don't see why a little help from parents can make you poor. Instead, it's necessary, cause help from them will give you time to get more dedicated on what you want to do.
