Keep your family and money separate. It usually always ends poorly otherwise.
My parents can't work, for example. They're both disabled and rely on food stamps plus medicare just to survive. This puts a rather large financial burden on me at times to say the least, because I would rather not see my parents starve to death.
If only we had a government that took better care of people in poverty. Imagine that.
Have they tried getting SSDI? No one gets rich off of that, but it is one of the major government programs to help support those with disabilities.
And then there's the difference between loaning and gifting money.
