No that's paid for by tax. Or at least it should be if the government isn't trying to bail out it's budget. A government taking loans should only go towards projects increasing its income higher than the interest. Same as with buisness.(current Tories dont seem to get this)Or put in a bank and loaned back to governments who are having to pay tax credits because the money they just got loaned should really have been paid to employees by the employer......and incurred NI.tax employer/employee contributions as well.
In this case the process would be : buisness takes a loan, expands, hires workers, generates wealth. New wealth of workers and buisness is taxed and lower wage workers are topped up with tax credits. Company pays back loan with interest and generates more income to expand or invest while original invester also has more money to expand or invest.
More jobs, bigger economy, less benefits.
If there was no loan they would all be unemployed and taking unemployment benefits hurting everyone.
Where tax credits help over minimum wage(in this context, what they should be paid, as you put it) is that they help struggling buisness as they should pay less tax where such a buisness might go bankrupt under minimum wage hurting everyone.
Obviously moving tax around doesn't help with this but balancing minimum wage and tax credit is about balancing what the government pays to help buisness thrive and ensuring that buisnesses pay their fair share towards it's workers.
. i answered this point in my previous post. unless they are bailing out the budget they shouldnt use tax for this.
