Not sure what the snark is about from you, but it was funded with more than 10 years of hard work and savings, setting a budget, coming up with A, B, C and D plan options to put it together, not being able to predict what exact elements I would be able to afford, constantly adjusting plans, and buying key pieces at a time as opportunity and funding was in place. Other people take vacations, buy nice cars and spend their money on other things. I put all I had into the studio. I found a 1500 square foot facility with floor dimensions I wanted, and I designed the interior myself. It started humble, doing track work for other artists. Also did a variety of other work, from audio restoration projects to mixing projects to solo artists and combo groups. 2-3 years in I was making money, above break even. After some years when the next generation preferred playing ukeleles in their bedroom into Garage Band to post on YouTube, and instrumentation of the day didn't have sources that generated above 90dba that required a studio to record in, I started to lose enough client work to make it not worth the monthly cost to maintain a facility.
You should try it sometime. It would change your attitude.
