Why high price for software?

I believe that the pricing is reasonable as they are continuing to update Ps and Bridge (which comes with it free) - additionally, the camera raw upgrades along with Ps. This seems to be about 4 times a year. That requires time and highly skills programmers ... which is a major expense on Adobe's end. THAT is why the price "seems" high. I personally pay 32.00 a month for the full suite - that is an unbeatable price for the continued improvements.

I think this is a very professional software so the price for a company its okay with different licenses and many users its not so high.

Professional versions of *anything* are always more expensive than consumer-grade options; usually much more. This is true of electricians' screwdrivers, barbers' scissors, industrial paints or anything else you might name. There are far cheaper homeowner versions of all these things, but professionals still pay the premium for the pro tools. The reasons are many, but they come down to usability, reliability and capability. All of these require the best design and engineering teams to keep up with expanding user needs, plus extensive support and distribution infrastructure. None of that comes cheap, so the product inevitably costs more. But when your livelihood depends on it you don't waste money or time on cheap tools that can't do the job. Whether you consider a professional to be an "ordinary user" or not depends on your point of view, but Photoshop is built for people who make their living with it. Adobe makes a smaller but highly capable version called "Photoshop Elements" for family and amateur photographers who don't need the extended capabilities of Photoshop.

we pay 23/m per user. and it's a little bit expensive...

It is about 10 dollars a month and constantly updated.
