Logically you would think this may help women but .. Let me explain. I come from a part of India which supposedly experienced bad sex ratio in 1920s-40s. I learnt from my parents and Grand Parents that the greedy parents of Women were 'selling' their daughters for higher money to older widowers. Also women were bought from other states. These were captured well in Telugu Drama 'KanyaSulkam' as an effort to get rid of evil. Apparently changes in sex-ratios don't result in correction of power balance.
