Yes, but perhaps not as the ones you discuss. The South China Daily Post has an article:
Cai Yong, an associate professor of social demography at the University of North Carolina, said men from lower social classes faced the most difficulty finding brides.
“They tend to be at the bottom of society and do not have the skills to compete,” he said. “They mostly come from rural areas and are less well educated.”
Jiang [a demography professor at Xian Jiaotong University] said bachelors were also more likely to suffer health problems.
“Without marriage, these excess males will suffer poorer physical and psychological health,” he said.
“Chinese people rely on their spouses and children for support in old age, but these men have no such relationships.”
Thus the problems will grow, with the government having to step in and provide for millions of unmarried, poor old men in the 2060s and beyond.
Cai sought to dismiss a widely held assumption that China’s surplus of single men was to blame for social instability and crime.
“The correlation between gender imbalance and crime rate is not strong,” he said.
