Ah... Laundering money you don't care about a negative return, as long as it is a stable return.

The compression ratio is the difference between the static air pressure at the front of the engine and the dynamic pressure at the rear of the engine. The dynamic pressure includes velocity in the calculation. It's not really comparing apples with apples. So you can not just multiply the values out.
900psi is more like rocket engines?

It's important to note there is more accelerate than squeeze. It's almost an order of magnitude less than a car engine. The back end of the jet is open with only some blades blocking the exit of the heated gas.
Some people get the idea the pressure is massive but it's more like bike tyre pressure, so jet engine shrouds don't need to be very strong.

What about "People with depression more likely to drink alcohol"?
