This sounds like a way to hold onto more money for rich people and making the poors pay for it. Unless they have a really sophisticated way of applying sales taxes to disproportionally target rich people and not just raise taxes of everyone’s vices (smoking, drinking, propane, etc) further. 

I might be wrong but it’s my gut reaction.

That would be correct. Since everyone needs to buy certain things (food, clothes, etc.) the tax burden shifts to the poorer people. This would also disincentivize spending and probably tank the economy.   

The better off would benefit since they could afford more durable goods that cost less in the long run. Increased sales tax would encourage them to by better more durable goods and use them for longer.
