The more money you have, the more diminishing returns on getting value out of it. Hence, charities, which offer to do Great Things with your money. Most don't. But anyway, what is one to do to get high yield out of lozza money? One thing to do is give lots to one's kids. Friends are also a good target, if they are short on money -- you know your friends and can see if you give them money for a specific thing it really will be a worthy purchase. There's surely other good ideas, low excess creativity now though.
If you're rich and short on solutions, I can help *grin*, you know my email....... *waves*
