Morethan, you asked the question of "Ok, my dh has a small business and I am sahm.
During my week I must clock approx 24 hours doing business related work to assist him. My problem is that yes he could do these things himself, but the time I save him he can use productively in the business himself and in fairness he does.
He draws a wage from the business but doesn't take any dividends, the business could stand me taking 24 hrs pay at NMW. This wage would entitle me to more tax credits, which would definitely come in useful."
It doesnt mention it being to take advantage of your tax allowance but being done with more tax credits in mind. If his SE business can pay out 24 hours extra then he could employ you anyway and you could cease claiming benefits. Thats why the system should change as its not there to support low earners earning the maximum they can but just allows people to manipulate the system to gain maximum payments.
All parents raise their children working or not. Theres no special "value" placed on SAHPs as it doesnt warrant it. You can parent and work at the same time easily, being a good parent is about many things. Nobody seems to value the men that are sent out to work simply because they are male. Yet they are no less of a parent and actively ensure they keep a roof over their childs heads and food on the table.
Its not about being rich to avoid working but with all life choices comes finaincial impact, if you cant afford to provide for your children then you cut your clothe accordingly rather than go ahead and have what you want anyway and have others pay for it. Lots limit the number they have, save to cover time off, work different shifts to partners etc so its silly to say its only the rich that can have chidren.
