The truth is that every parent that is wealthy wants their children to continue in their legacy that is why there is generational wealth in most homes today, and it also depends on the financial discipline of the parents just like you stated because if they are not disciplined in their finances, it could be difficult to pass wealth to their offspring. In the past, most rich kids believes that their parents wealth is also theirs and that mentality misled a lot of children such that they don't work anymore because their parents already had money but it made them become so lazy and unable to manage the wealth after the demise of their parents but in this modern day, parents even start teaching their children how to make their own money right from a very tender age and it has really helped because they now understand what it takes to make their own money which made them to be cautious about their money and applied disciplinary measures that paved way for generational wealth.
Yes , you are right. There are thousands of people who are rich but their sons are not hard working because they have land and they are selling their land and they are becoming poorer and poorer with time. In the comparison, there are also rich people are available in the society and they got many lessons from their father and father is king in the society because all brothers are doing effort for money. Money is important in life but every person have to sell anything to earn money but when person has more money than expectations then he will be idol . They have no discipline which will make them successful in life and they are losing their abilities with time.Being poor is very easy but being rich is very difficult and need discipline for this.
