Has the worldwide recession affected MAs (less people willing to spend for classes, etc)?

Has it affected your own training? How?

It definitely has at my TKD dojang, but my Judo dojo is a-boomin', being that Judo is cheap and widely available.

The only thing that it affected for me was my ability to study BJJ and SAMBO.

I can share my equipment and what little experience I have with people for no money at all. It only costs effort.

Could do with a bit fewer schools in town anyway; just driving the main road through town I see about 8 schools of various styles, some serious, some McDojo.

Has it affected my personal training? Somewhat. Less willing now to spend the money for competition and seminars, but regular classes are still ok.

I can't really afford to go to tournaments at the moment, and driving the hour+ in my Jeep to get to no-gi BJJ is also pretty unobtainable. So it's affected me in little ways, but I'm still going to keep judo up for as long as possible.

Not so much at my gym, seems more people are turning up than before. We're on holidays now, so I'm sure a lot (along with the regulars) will be back in training again come the beginning of the new year!

The recession mostly affects people at the bottom of the socio-economic ladder, whereas martial arts (and MMA especially) is generally a hobby of the middle class. This is what has allowed the UFC and the sport to grow, even through these turbulent times.

Ditto. I have myself and both of my kids in Judo for less than MMA used to cost just for me.
