I wonder how long the plank of wood they've stuck on the back would last with the likes of the odd ladder and bunch of krabs etc. placed on it during the course pf normal usage.
A point worth noting about all of these billionaires is that they don't have their wealth as cash in the bank. It's mostly shares. So if a left leaning government decided to 'windfall tax' them, they would have to dump shares. A sufficiently large tax bill could bring down some quite large companies, which might not be a good idea.
Bill Gates is very philanthropic. Steve Jobs was not.
Their wealth is in shares because dividends are "tax efficient" - less tax is paid on dividends than is paid on a salary - if dividends were less tax efficient they would shift away from shares.
But it is not about a "windfall tax", what is needed is a global (so it will never happen) reform of the whole approach to taxation, using taxation to encourage better benefits for the many - things like higher taxes on any executive income (from whatever source) that is more than say 100x the pay of a companies' lowest paid employee or sub-contract employee. Such taxes could be introduced at a low level and gradually increased to avoid cliff edges.
What I would want to know before buying that Rolls is: can I get all my caving gear and that belonging to any passengers in the boot along with some tackle bags full of rope?
Off topicbut with the mention of "investments" a heads up to premium bond prize money now up to 4%, and its tax free. But you have to really be a big hitter to get prizes. The max investment they allow is £50K and for good reason as the odds tend to pile up in the investors favour.
