Yawn, happy to tax the person more who is slightly bigger than you? Who'd have thunk it. Noone cares unless its their money of course.
Sizeable businesses need sizeable profits. A single piece of kit for our business can cost £250k easily, a filling/labelling line, a vacuum mixer, a 60mt heated tank... and its gone. We make north of that threshold and the profit is absolutely required, fundamentally so for the long term continuation of the business...and yes, heaven forbid, also keeping me interested by paying me commensurate to the large risks we take. Reduce after tax retained profit and you can starve a business from having enough reserves to invest to sustain itself, or enough cash to grow. The fixed assets of a reasonable sized business constantly turnover and that happens only with reasonable profits. I don't much like people describing my profits as superfluous (based on arbitrary numbers) vs their own simply because theirs are lower, on what basis is that a striver's economy? Rather like the lifetime pension allowance and other such ill-thought out policy, all it does is encourage people to put the brakes on when they hit the states prescribed buffers,
If you've ran a mid sized business before you will also know that there comes a point where a business becomes far larger to support than even the backstop that a wealthy owner can provide. That is to say liquidating all your assets, houses, cars & clothes off your back may only fund the business for a few days, at best a month. So would you run such a business light on cash? I wouldn't and don't. Hence again healthy profits and healthy cash in the bank is necessary, too large to bail out from owners' pockets so an insurance policy of appreciable cash on hand is required to protect against unforeseen events, a slow year, or whatever...It is lazy IMV to conclude £250k is some sensible number to start ramping tax up at. £250k is a relative number, for a small business (and a socialist) it looks like a fortune, to somebody running a medium sized manufacturing business you may start sweating buckets if you made less than that one year, that'd be dangerously close to the wire.
I may have agreed about the notion of helping the gov out in troubled times too, if I wasn't cynical enough to know that when they get their claws into you then they do not let go. Taxes will be a lot quicker to go up than they'd be to go down.
