Here is the thing, you never know....I don't pile up cash or stock over $100k or so. With a minor in history, I always fear our monetary vehicle could go the way of the Weimar Republic (worst possible scenario). I reach a certain level of cash, and I buy an item that can generate income, or the service it provides can be used to generate income or trade. Saved up $15k, bought a skid loader, save up $6k, split ownership of a 28 ft. gooseneck. $10k, bought a tractor. My next purchase, is an excavator at about $20k. Next, a car lift at $4k, etc...
Luckily I have the acreage/shop to put it on/in. I personally don't trust anything where I don't have full control. Rent houses, land, equipment, greenhouses, items that provide services, food on the table, or a roof over your head are where I invest. This is where the last thing that people with no money will still be willing to use their limited funds.
I'm pessimistic enough to think there will be something come down the pipe in the next 30 years that will wipe out investments, pensions, and the value of cash money.
