Yes, most people will have to work their normal jobs until retirement, but, if you keep in bitcoin you will be able to save enough for a down-payment for a house, or to have a good saving for your retirement (very important!) and pass along to your kids, all thing we currently can't with fiat, bitcoin is hope not because it will make you rich but because you can work, save, and benifit from that in the future, it allows you to think, plan, save and have hope for your future.  

 I recently bought a house after saving for the down payment in dollars.  The savings came from avoiding debt and investing in my education and personal development to land a good job.

Saying you can't save for a house in fiat is just not true.
