[Science fiction in general] How easy would it be to get rich in a galaxy spanning empire with trillions of inhabitants? Could sell some product for only one credit and become a trillionaire?

Same reason you can't sell something today for a dollar and make a billion.

Cost to produce, cost to distribute, cost to advertise, markets you can't sell in, markets who don't want your product, copycats producing the same for .20c less, cost of legal settlements and fighting off patent trolls, cost of physical protection, cost of someone to manage all this...

I mean, in theory it's possible, but there's a whole world out there (or several worlds in your case) full of people trying to take the same bite out of the same pie. The lucky ones pull it off, the rest are just the rest of us.
