The Mega Millions is now $130 million. Imagine having to give $13 million to maaser! (Yes, I know, taxes, etc it’s not $13 million).
I’d build myself a huge house, with lots of bedrooms. My wife and I love having guests over, but unfortunately our apartment is kind of small, and we can’t fit too many people. If we had a lot of bedrooms, we could have guests sleep over for Shabbos without a problem!
If I really had a lot of money, I’d start an exclusive kollel for the elite, the way it’s meant to be. I’d support them properly, so their wives wouldn’t have to work 3 jobs each.
