If someone comes along and asks for the piece of the pie, there is absolutely no reason to share it. Granted a stressful situation might be taking place when friends and family start asking for money but nobody is bound by any reason to hand over their money to them.
If you lose friends and family because of it?
Say you have friends and family and everyone has their own basic salary... now they come to find out youre rich, you have won a huge lump sum of cash... Of course everyone will come up to you begging for and asking for money. Now if they are shitty friends, they will no longer want to talk to you for not sharing...
Friends you didnt even know you had will come asking for piece of the pie.
