Quote from the1:
Barriers to entry are pretty much identical. If you got 5 grand and a few tools you're good to go. It's staying in the market that requires the craft. The niche in this business is doing high quality work you can hang your hat on. Put two carpenters on the same crown molding mitre and you'll get two completely different results -- just like trading.
The barriers to entry are much higher in construction. You can buy a toolbelt but without getting a client you really aren't in the construction business. However, an Etrade application is a click away.
Any real economy business has higher barriers to entry.
Secondly, once you establish yourself in a real industry you are likely to have some recurring business model. Unfortunately trading is not as recurring.
Trading is definitely a less stable business model. This is why publicly traded trading/market making firms have lower PE's than real economy firms.
But trading very clean and very leveragable, which real economy businesses are not. If your strategy really works it's easy to x10 it. It's much harder to x10 a successful real economy business.
