That would be a disgraceful subsidy of an industry which concentrates on political lobbying rather than just being good at doing its job.The other pre-budget consideration I feel is the complete removal of VAT on new homes -
The solution is for the State to buy in factory built homes from major European supplier and have them erect those homes. That would avoid the labour supply constraints on the private sector which would otherwise be caused by a massive State house building program. We'd also end up with a superior quality product.
Have a look at this site for what can be achieved using 21st century building methods (or even 1970's building methods as opposed to the 1870's methods we use).
Look at that site and ask yourself what it would cost if the State was buying 60,000 units based on five or 6 base designs.
