Aye, the removal of subsidies combined with an equalisation of animal cruelty laws would send the price of meat and dairy through the roof.
The whole subsidy thing is bizzare anyway ...
It doesn't make meat and dairy genuinely cheap for one thing. The only source of subsidies is taxes. That means that ALL taxpayers are simply pre-paying, through their taxes, for the meat and diary elements of their's (and everyone else's) food.
The main beneficiaries are land owners. Taxpayers are basicaly providing them a way to lock off vast amounts of land and make money from doing so. Bit of a double whammy on the taxpayer that one. It makes land artificialy in short supply and that sends the cost of land for housing, leisure and industry through the roof.
The secondary beneficiaries are arable farmers. A meat eating population needs about ten ten times more of their product than a vegan population would.
The rub in that being that alongside the meat industry and the big landowners the arable farmers have vested interest in suppressing the spread of veganism in any way they can.
