I agree with childcare being tax deductible. I physically cannot get to work without having childcare. I earn too much to get any tax credits but not enough to pay for full childcare. So this would have been a great help for both low and middle earners.
However I can work without my cleaner. I suspect it is only higher earners who have cleaners and I just do not think at this time that supporting people on higher wages is a priority. I can afford to pay for my cleaner, if I couldn't I would do it myself , no great hardship.
