I love this as a science fiction thought experiment but altering the male/ female ratio will never happen.
If someone tried to implement it- aside from the obvious problem of authoritarianism- the resulting male minority would live life in romantic "easy mode" so people who want the best for their kids would want male children and rebel against a system more likely to give them female children who would find romantic prospects difficult.
I suppose if someone invented a way to alter sexuality to allow straight women to opt into becoming gay the romance problem could be mitigated, but I'm guessing that this is impossible given the human brain is only so neuroplastic in adult years.
