Big money 1/8 races (or 1/4 for that matter)? Who is getting the big money? Trying to race to make money? You are either A; in a very, very small group. Or B; a poor businessman. Most of us race for fun, myself included. If it wasn't fun, I'd quit. Money is just a nice side benefit which the majority never sees. Personally my belief is 1/8 is insurance driven. I don't hate it, just like 1/4 better.
