Is it?

It's not really compared to an average person's life, but in SV tradition never let the chance to subtly flaunt a wealth gap pass by freely

(This is the part where you say "Yes, having lived both <insert revelation>")

Has 50M: wishes they had 250M

50m is the upper echelons of private chaffeur money, 250m is the lower echelons of private jet money.

It depends on the kind of lifestyle you want to live, I guess. If you want to live in a $30M mansion estate with 24/7 domestic staff and have several vacation homes around the world, $50M might not cut it, while $250M should cover it just fine.

If you have a philanthropic bent and want to be able to fund various charities to the tune of $5M or $10M per year (in addition to a reasonably luxurious lifestyle, though considerably less than the above hypothetical), $50M might not be enough to sustain that over time, but $250M probably will.

I think it's fair to say that there's not much difference between net worths of $25M and $50M, or between $50M and $75M. But jumping an order of magnitude from $50M to $250M will let you live a very different kind of life, if you so choose.
