And some will set up a charity, but people like Bill Gates have never spent a significant portion of their wealth on that. Again though, that may be a logistical problem - they can't spend money fast enough whilst not splurging it.
Of course, the solution is simple; have the companies pay their staff better. Or give the staff stocks themselves, to be force-bought by the employer when they leave / get fired, and have it pay out dividends monthly to stipend their base income. This gives the employees representation in the board of directors as well, which is much needed in the modern capitalist system.
That is not "hoarding cash" - keeping your net worth under the mattress or in a savings account is hoarding cash. Perhaps, at the margin, a money market account.
This has been its use for a long time in any publication talking about money.
I know when you say "hoard wealth" you really mean not spend their wealth, because I'm not really sure how you "hoard wealth", as being wealthy basically means you've got stores of valuable assets... or a hoard if you will.
The two phrases are definitely not used interchangeably.
Indeed. Hoarding cash is for fools. I'm always bemused by the claims that wealthy people hoard cash.
