To contrast what it takes for a "working man" to go and see a concert now vs. then...
When I was a teenager 14-19 in the 70's, the Minimum wage jobs I had an average of $1.80/hr. Concert ticket prices in my teenage years ranged from $6 - $8.50 (including all taxes and fees!!!)
So going to a concert then meant paying out about a 1/2 of a days gross wages.
Today the federal Minimum Wage is a paltry $7.25/hr. Let's double that to $14.50, as many states have minimum wages now more than the Federal $7.25.
So a $300 ticket today is around 20 hours work, or 2.5 days gross pay.
But the $300 ticket would easily be a week's gross pay for anyone earning the $7.25 Federal Minimum wage.
And, the seniors today who knew of Rush in the 70's, who are living off of Social Security, could not afford a $300 or more ticket. The working man audience for the 70's, in many cases are now shut out from Rush. Who says you have to keep the same audience anyways!!!
