I think prices are still rising. That said, the market is split. The agencies are businesses and hence pay taxes, the direct tutors usually do not declare income and operate in a black market/cash in hand fashion. Most STEM students are financially naive. To them the prices already feel high and they seem reluctant to go truly maximaly price seeking. This in turn limits the agency market as the gap would grow to wide.

While in theory there are great alternatives in online materials etc for math remediation, the truth is most of the students using these tutor services don't lack potential but motivation. The parents send them to tutoring, the student does not want to be there and so wiuld also not fi d or consult alternatives.
