Actual problems in the field of construction education and ways to solve them
At present, the general level of culture and education of the bulk of the people is very wide, many of the achievements of our educational system, which we are accustomed to be proud of, have turned out to be negative, costly, unpromising, dead-end and erroneous.

Free higher education depreciated it and made it accessible for both capable and mediocre people, reduced the overall quality of specialists, and, consequently, the quality of their products.

A large number of specialists with higher education, in particular civil engineers, led to their overproduction, use outside the profession, reduced their prestige and level of remuneration, increased budget costs for training an excessive number of specialists with low returns.
