Or change something. But yeah, I agree that leaving a country that you don't like is a good solution. I did that myself.
> There is no justification for tax evasion
The basics of philosophy behind taxation state exactly the opposite: it is an obligation of a business to evade as much tax as possible - as long as it is legal.
As I see it, the general philosophy of taxation in old Europe is this: any euro that you take home is a theft of state money. Ideally you should pay 100% of your income and then some. It's okay to receive salary though.
Are you sure? I'm paying 48% as income tax, and then 21% as VAT and some additional taxes on gasoline, electricity, LPG, car, motorcycle, house and water. Additionally I'm forced to buy health insurance and cannot pay for medicine out of my pocket, insurance is only way to go.
If I invest my money (buy ETF, for example) I need to pay tax on imputed income over my open positions on the stock market (no matter, goes actions/ETFs/options up or down, I pay for open positions, not for my income from these positions).
If I have more than 57K€ in the bank (with 0.5% interest when official inflation rate is about 4% and real one is more like 10-12%) I need to pay tax on that money (not for the interest earned, but for sum on the account!).
Looks like it is not Ok to receive salary if it is a notch above poverty level, too.
Oh, and now I need to pay duties (on top of VAT) on each purchase in non-EU internet shop, no matter how cheap it is, and there is minimal duty 4€ per item. So, buying something small but unique on AliExpress is very costly too. And it is not protection of local brands — because almost nothing is produced here, especially for DIY hobbies (my case, but I'm sure everybody can name other group of goods which has good selection over aboard).
I've get free samples of some technical fabrics from USA (could you buy then in EU, by meter and as privet persond and not a business? Nope) and payed 14€ to the state: like 2€ VAT on FedEx shipping costs (goods are FREE!) and 12€ fix to process this transaction. And, no, it is not FedEx fee, it is local custom fee, it it the same for official national post service. Nicccccce.
