"Nobody wins in a race to the bottom, especially the countries willing to cater to bottom feeders. It's ultimately bad for everyone. Your 'economic facts' are terrible things for an economy."
Someone wins every race. Instead of "race to the bottom", which is just an emotive term unions and public sector workers cling to for comfort, look instead at the prize of the winner. A share of most of the corporate tax in Europe. Even at a 0.5% tax rate that is a lot of money. Economic facts often are terrible for socialists, but that doesn't make them untrue and it certainly doesn't make them escapable. Keeping high tax rates will mean people and companies go elsewhere and then we'll have to massively cut spending to account for the lost taxation.
"By continuously reducing the private sector tax contributions to get companies you're catering to the most undesirable sort of businesses."
Private sector tax contributions are the only kind of tax contribution that actually exists. If you don't have it, then you have zero tax revenue and can afford zero services and spending. Tax paying businesses are, economically speaking, exactly the kind of business we need to attract. Remember, public sector staff don't pay taxes (if everyone worked for the state and paid a 50% tax rate, where does the other half of their pay come from?).
"You're going to have to acquiesce to their demands or they'll threaten to leave and they'll turn your citizens against you out of fear of losing all the jobs that were created."
If a company headquarters in the UK and pays 0% corporate tax, but creates jobs paying £!Bn of income taxes, then it simply doesn't matter that the company paid no tax. It the jobs and the taxes paid by them which matter.
Ultimately, unless you are a higher rate tax payer for most of your working career, and you spend all of that career in the private sector, then you are a net beneficiary of the state as you don't pay enough taxes to cover the services you receive cradle to grave. That is just a fact.
There is a global competition for tax revenues, from both corporates and higher earners, and if the UK doesn't start to compete to win that race, then the prize, and all the tax funded services which accompany it, will go elsewhere.
"Soak the rich" may be an easy rallying cry, but its failed whereever and whenever its been tried.
