Exactly. There is something dearly missing between Masters to PhD. Many European PhDs are now 3 years while US PhD tends to be 5 year. It would have been great if PhD degree standardized to 5 years but was broken down into two separate degrees of 2+3 years.

Although the time to completion seems quite disparate between Europe and US, the difference isn't nearly as stark as it appears.

Nearly all Europeans enter PhD programs with a Master's degree in hand. At least in psychology (my discipline), US PhD programs will admit candidates directly from undergraduate. The overall time from bachelor's to PhD is similar when you account for these differences.
